How many square meters of a board are in a cube: dimensions of products, number of parts, calculation of volume and area. Edged board How many in a cube of 6 meters

Construction works require the solution of many different issues, among which the most important task is the selection and purchase of lumber. It is not difficult to calculate how many linear meters of boards and timber will be needed during the construction process. That's just the price of commercial wood is indicated for 1 cubic meter, and this often causes difficulties for novice home craftsmen. The ability to correctly select and calculate the amount of edged or unedged lumber in a cube will save money and avoid a situation where, after completion of construction work, a pile of unused boards remains on the site.

Classification and characteristics of lumber

The very name "lumber" suggests that this type of construction raw material is obtained by longitudinal sawing of tree trunks on circular or band saws. For the production of boards and timber, several sawing methods are used:

  • tangential (in a circle),
  • radial.

Tangential sawing involves the movement of the saw tangentially to the annual rings of the tree, which reduces the amount of waste, and hence the cost of building materials. The boards obtained in this way have a beautiful, pronounced pattern, therefore they are often used for finishing purposes. Disadvantages of circular sawing include the wood's tendency to shrink and swell, and a significant difference in texture as the cutting tool approaches the center of the log.

In the sawmill industry, several methods of sawing the trunk are used.

With radial sawing, the cutting line passes through the core of the tree, so the output of boards will be less and their price will be higher. However, if it is necessary to obtain high quality wood, this method is used. This is due to the fact that, compared with the tangential method, radial sawing boards have halved swelling and shrinkage rates. In addition to the sawing methods discussed above, a mixed method is also used, which combines the advantages of the first two.

The concept of lumber actually includes not only the traditional molding, which is most often seen in the construction markets. Full list products that are obtained by sawing logs, includes:

  • board;
  • timber;
  • bar;
  • lagging;
  • croaker.

The last two types of lumber are waste, which absolutely does not prevent them from being used for certain types of construction work, as well as for finishing purposes.

Boards

Boards include rectangular lumber with a thickness of not more than 100 mm and a width to thickness ratio of at least 2:1. Depending on the degree of processing, the board can be edged and unedged. The first is a finished product without bark and with evenly sawn edges, while the second is a "semi-finished product" taken directly from the saw frame.

Edged board has smooth edges and a constant width along the entire length of the lumber

Most often in construction boards of such standard sizes are used:

  • thickness - 25 mm, 40 mm, 50 mm, 60 mm;
  • width - from 75 to 275 mm with gradation through 25 mm;
  • length - from 1 m to 6.5 mm in 250 mm increments.

Boards of other sizes can be obtained by cutting or planing standard lumber, as well as by making individual order for cutting round timber.

Unedged board has a lower cost, but without finishing, its scope is limited

The parameters of lumber used in construction are standardized and determined according to the current GOST 8486–86 for softwood and GOST 2695–83 for hardwood.

bar

Timber is called lumber, the cross section of which is a square with sides of at least 100 mm. The size of the beam in the diameter is unified and can vary from 100 to 250 mm in increments of 25 mm. The standard defines the length of products of this type from 2 to 9 m, but lumber is most often used. square section with a length of not more than 6 m. In some cases, products with a section of 150x100 mm, 200x100 mm or 200x150 mm, which, according to the existing classification, are much closer to the sleepers, are mistakenly referred to as timber.

Cant is ideal material for the construction of frames and other wooden structures

The bar differs from the bar considered above only in that its cross section does not exceed 100x100 mm. The typical length of the bar is also 6 m, and the size in diameter ranges from 40 mm to 90 mm in 10 mm increments. To simplify the classification, bars are often referred to as a rail, in which the cross section has a rectangular shape, and the ratio of thickness to width is at least 1:2. The standard range of edges of softwood slats looks like this: 16, 19, 22, 25, 32, 40, 44, 50, 60, 75 mm. For hardwood lumber, products of increased width are additionally provided, and the product line itself looks like this: 19, 22, 25, 32, 40, 45, 50, 60, 70, 80, 90, 100 mm.

A variety of bars and slats allow you to strengthen and make any wooden structure as stable as possible

Obapol and croaker

Obapol represents the very first cut of round timber, in which the outer surface remains untreated. Unlike obapol, the croaker can have a cut on half of the second side or an alternation of processed and unprocessed sections from the side of the bark. The value of obapol and slab in construction is secondary, since it is unaesthetic appearance and reduced performance characteristics allow the use of lumber of this type only for auxiliary purposes. Most often, slab and obapol are used as a fastening material, as well as for the manufacture of formwork, battens or flooring. scaffolding. This material is also interesting as decorative material for decoration of walls, fences and other vertical structures.

Despite external unsightliness, slab and obapol are widely used for secondary construction tasks.

Technology for calculating the number of boards in a cube

On the wood market, both edged lumber and unedged boards are presented, along the edges of which there is a wane. Depending on the type of wood products, several methods are used to determine the cubic capacity.

How to find out the number of edged lumber in a cube

The algorithm for determining the cubature of lumber is based on the formula known to every schoolchild for finding the volume of a rectangular parallelepiped. In order to find out the cubature of one board (V) in a cube. m, it is necessary to find the product of its length (a) by the width (b) and thickness (h) in meters V=a×b×h.

The desired figure will make it easy to calculate how many boards of this type will fit in one cubic meter lumber. For this, 1 cu. m of lumber is divided by the volume of one product. For example, if you need to find out the cubic capacity of one board with parameters 6000x200x25 mm, then by substituting these numbers into the formula, we get V = 6x0.2x0.025 = 0.03 cubic meters. m. Therefore, in one cubic meter there will be 1 / 0.03 = 33.3 of such products.

The grooved board has a groove on one side and a ridge on the other. Since both of these elements are approximately equal to each other, their parameters can be neglected. That is why the size of tongue-and-groove lumber in diameter is measured without taking into account the locking part.

In the case of boards that have the same dimensions, the calculation can be simplified by substituting the dimensions of the lumber stack into the formula. Of course, at the same time, its laying should be as dense as possible, otherwise the gaps between the individual elements will affect the accuracy of the calculations. Given that the cost of individual types of wood reaches tens of thousands of rubles, such an error can result in a pretty penny.

To simplify the calculations, you can use special tables that allow you to quickly determine the cubic capacity or the amount of wood in 1 cubic meter. m lumber.

Table: the number of edged boards in 1 cu. m lumber standard length

50x20016,6 0.06
50x25013,3 0.075

The cubature of timber of standard sizes can also be determined using the table below.

150x2005.5 0.18
150x3003.7 0.27
200x2004.1 0.24

Very often it is required to determine the surface area (floor or wall) that can be covered with a board of one thickness or another with a volume of 1 cubic meter. m. To do this, you can use the formula S \u003d 1 / h, where h is the thickness of the lumber. So, one cubic meter of a 40 mm board will be enough to equip S = 1 / 0.04 = 25 square meters. m floor. To facilitate the process of calculating the area allows a table called a cubature. It contains data on the cross-section of boards, their number in 1 cu. m and the desired area that they can cover.

Method for calculating the cubature of an unedged board

Unedged lumber is not trimmed along the edges, so not only the size in the diameter of individual products varies, but also the width of different parts of one board. In this regard, it is possible to calculate the volume of a stack of raw lumber only approximately. The same applies to calculating the cubic capacity of a separate unedged lumber, although the error in this case will be much smaller.

So, to calculate the cubature of an unedged board, there are two constants - thickness and length, and one variable - width. To avoid complex calculations using differential algebra methods, the last parameter is simply averaged. To do this, the board is measured in several places and the arithmetic mean is found. For example, for a board with a diameter at the base of 400 mm, a width of 350 mm in the middle and 280 in the top, the calculated value will be (430 + 340 + 260) / 3 = 343 mm. Further calculations are carried out in exactly the same way as for edged lumber.

Most often, the width of an unedged board is determined only on the basis of measurements along the edges of the lumber. It should be noted that the accuracy of calculations directly depends on the number of measurements, therefore, in critical cases, their number is increased.

If it is required to find out the cubic capacity of a package of unedged wood, then the products are stacked on top of each other in such a way that the following conditions are met:

  • stacks must be aligned along the front end;
  • boards in a stack should not overlap;
  • it is not allowed to change the width of the package along the entire length of the lumber;
  • the protrusion of the outermost products beyond the stack should not exceed 100 mm.

By measuring the height, length and width of a package of unedged wood with a tape measure, the approximate cubic capacity is determined using the formula V=a×b×h. To find out a more accurate value, the result is multiplied by the stacking factor, which can be found in special tables.

When carrying out construction work on the construction of a residential building, a specialist needs to perform a large number of various tasks, some of which are: drawing up and calculating the estimated cost before the final finishing of the premises of a residential building. Without fail, calculate the required number of various building materials which is quite difficult to do. Therefore, such knowledge - how many boards are in a cube, is very important for a specialist who is engaged in the construction of a residential building and wants to do the job as efficiently as possible and quickly in time.

Buyer's club: existing types of boards

To calculate exactly how many board pieces are in a cube, you need to know not only what exactly the board cube means, but you should understand important point that exist different kinds boards and what is the opportunity to purchase on the modern market to perform a variety of construction work. It should be noted that the cube of almost all materials, regardless of the type of material, is calculated in the same way, that is, according to one specific method. The types of boards have no influence on the calculation of the cubic capacity of this building material.

The non-grooved type of lumber is: timber, various edged boards, as well as unedged boards (they are an exception when calculating cubic capacity, because this process is a little different). Grooved types (which have special grooves for the joint) include: modern lining, blockhouse, flooring material, as well as imitation of natural timber. When you choose to buy a tongue-and-groove type of building material, then you need to pay attention to the fact that when making a calculation, only the working width of the board without a spike is used. If we talk about a blockhouse (imitation of a log), then when calculating the cubic capacity, only the thickness at its highest point is taken.

How many boards are in 1 cube: performing a calculation

Any person, since his school days, understands how the cubic capacity is calculated. For this procedure, it is necessary to calculate quantities such as: length, width and height. A similar principle is also used to calculate the cubature of 1 board. It is recommended that when performing such calculations, convert all available values ​​​​in meters. Cubic capacity of 1 board, which has a section of 150x20 mm. and a length of 6 m., is calculated as follows: 0.15 is multiplied by 0.02 and by 6, so that the cubic capacity of this board will be 0.018 cubic meters.

Apply the volume formula V= L*h*b (where L is the length, h is the height, b is the width).

L=6.0; h=0.02; b=0.15.

Thus, V \u003d 6.0 * 0.02 * 0.15 \u003d 0.018 m 3.

To determine how many boards are in one cube: 1 m 3 is divided by the cubic capacity (the volume of one board).

1 m 3 / V = ​​N pcs.

1 m 3 / 0.018 m 3 \u003d 55.55 pcs.

Thus, the number of boards in one cube is 55.5 pieces.

It is quite easy to find out the cost of a certain type of board when its volume values ​​\u200b\u200bare known: 0.018 is multiplied by the price of 1 cubic meter. When 1 cube of a certain type of board has, for example, a cost of 5500 rubles, then the cost will be 99 rubles. At this point in the calculation, there is some trick of sellers and managers in hardware stores, because the cubic capacity of the material is rounded up to some integer values.

Such rounding can lead to such a moment that the price of 1 board (when 1 cube costs 5500) will be completely different values. In addition to all this, it should be noted that for various boards for construction, which make up a nominal length of 6 meters, in fact, the length is 6.1 - 6.2 m, which is not taken into account when selling this building material. This also applies to the acquisition of a significant number of boards. This is quite clearly visible if, for example, a 150x20 mm board is used. The number of boards in a cube is a value of 55.5 pieces. But, in a cube, 55 pieces are considered, which, when calculating, will have a value of 0.99 cubic meters. In fact, it follows from this that the overpayment for 1 cubic meter of this popular building material can be 1% of the real price. For example, 5500 instead of 4995 rubles.

To calculate the cubature for a non-cut-off type of board, slightly different methods are used. When it comes to buying 1 board, then measuring its thickness, as well as the total length, is done in the same way as when choosing a cut building material. In this case, the width for calculations is taken as an average - between a large value and a small one.

For example, when the width of the board at the end is 25 cm, and at the other 20, then the average value will be approximately 22 centimeters. When it is necessary to calculate the volume of a significant number of such boards for construction, then it will be necessary to decompose them so that the wide one does not differ from the narrow one, more than 10 cm. The main length of this material in the unfolded stack should be approximately the same. After that, using an ordinary tape measure, an accurate measurement of the height of the entire stack of boards is made, the width is measured (approximately in the middle). The result obtained will then need to be multiplied by a special coefficient ranging from 0.07 to 0.09, in direct proportion to the existing air gap.

How many boards in 1 cube: special tables

To calculate exactly what number of boards of a certain width, length in 1 cubic meter, various tables are used. Below are several such specialized tables, which indicate the cubature of the common and popular types of this material today. It is possible to calculate the volume of various boards having different sizes, for example, material for erecting a fence on your site, using the available formula, which is presented above.

How to determine the cubic capacity (volume) of the material? It is very simple if the material, as in our case, has right angles. You need to multiply the width by the thickness by the length. And to find out how much of this material is in a cube, you need to divide the result by cubic / meter. Here is an example of how to determine how many 50x150x6000mm boards are in a cube. We will decide in centimeters.

(Thickness) 5cm x (Width) 15cm x (Length) 600cm = 45000cc/cm

The cube is = 100cm x 100cm x 100cm = 1,000,000 cc/cm

(Cube/meter) 1000000: (Board) 45000 = There are 22.22 boards in a cube.

If you want to know how many square meters in a cube lumber, you need to divide the thickness of the board in centimeters by 100 centimeters. Let's say you buy a lining 12.5mm x 90mm and you know that its square meter costs 120 rubles. The solution will be like this.

Lining thickness 1.25 cm 100: 1.25 = 80

From this it follows that this lining in a cube will be 80 square meters. And that the cube of this lining will cost 80x120 = 9600r






Meters are linear, square and cubic. Starting a large construction site or even small repair should be clear in these terms. The ability to correctly convert the amount of certain materials into linear or cubic meters will serve as an excellent service in preliminary calculations of the cost of a planned repair or construction. For example, clearly understanding how many square meters are in one roll of wallpaper, you can quickly calculate their number required for pasting a room or an entire apartment.

Calculations can be done in cubic meters, square or running meters

If the upcoming repair or construction is related to the use of wooden materials, it is necessary to thoroughly study the recalculations from linear meters to cubic meters, since prices can be presented on the market both per unit of material and per cubic meter. The number of timber in the cube varies and depends on its cross section. The easiest way to find out how many boards are in a cube is a table, but if it is not nearby, you will have to remember the formulas.

What is a cubic meter

A cubic meter (abbreviated m³) is a unit of volume and is equal to the volume of a cube with an edge length of 1 meter. In accordance with GOST 8486-86 wooden materials must have measurable cross-sectional dimensions and lengths, so that you can easily calculate the number of boards included in the cube of the material.

To determine the dimensions of the section, it is necessary to retreat from the end of the beam at a distance of at least 10 cm and measure the width and height of the beam. Multiplying these values ​​​​by each other, you get the cross-sectional area of ​​\u200b\u200bthe beam, multiplying which by the length you get the volume of one beam. By calculating the number of bars in one cubic meter, you can easily navigate between the cost of one beam and one cube of beams.

A cubic meter is equal to the volume of a cube with an edge side of 1 m

Calculation of lumber for construction before buying them

Of course, the easiest way is to come to the developer to explain what you want to see in the final version and agree to the proposed project. But, if you independently understand the calculations of the required amount of lumber, then even at the stage of discussing the cost of materials and work on building a house, you can find out how real prices are offered by a construction company.

Many developers calculate the required amount of material in cubes, some consider it piece by piece, taking as standard the running length dimensions - 6 or 12 m. A clear understanding, for example, how much timber is in a cube of 150x150x6000, will protect against overpayments.

Standard timber 0.15x0.015x6 meters

The procedure for calculating the amount of timber in a cube

Despite the same principle of carrying out calculations, there are certain nuances in determining the cubic capacity and the amount of various lumber.

1. Basic formulas for calculating the number of bars in a cube

To determine how many boards in a cube, with bars of a certain section, you need to know three measured parameters: length, width and height. First you need to calculate the volume of one bar using the formula V = a * b * l (here V is the volume, m³; a is the height, m; b is the width, m; l is the length, m)

Beam parameters: length, width, height

How many pieces of timber in a cube is determined by the formula:

Where, A - the number of timber in a cube, pieces;

1 - one cubic meter, m³;

V is the volume of one bar, m³.

2. How to determine how many pieces are in a cube of timber 100x150

In the price lists of construction companies, for convenience, they indicate the cross section of the beam, that is, its width and height, for example, 100x150. Where 100 is the width in millimeters and 150 is the height. The length is most often 6 meters, or 6000 mm.

The volume of a bar 100x150x6000 will be 0.09 m³.

V = 0.1 m * 0.15 m * 6 m = 0.09 m³. Here 0.1 is the width, m; 0.15 – height, m; 6 - beam length, m.

In this case, how much material will “fit” in one cubic meter can be found by dividing the cubic meter by the volume of one bar:

Where, 1 is one cubic meter, m³;

0.09 - calculated volume of one bar 100x150x6000, m³.

The characteristic shape of the beam section 100x150

So you can easily calculate how many pieces of timber in the purchased volume of material by multiplying the number of pieces by the number of cubes. For simplicity and speed of calculation, you can use the table: how many timber in a cube table is 6 meters.

3. How many edged boards in 1 cube

A similar situation is in calculating the amount of edged boards in 1 cubic meter of wood. For example, the board used has the following parameters 100x25x6000 (width, height, length).

The volume of one board will be 0.015 m³.

V = 0.1 m * 0.025 m * 6 m = 0.015 m³

Quantity in 1 cube:

That is, a cubic meter contains at least 66 boards. When buying a cube of edged boards 100x25x6000, you should get 67 pieces, rounding up. For example, when buying three cubes, you should get at least 201 pieces, and when buying six - 401.

4. How many in 1 cube of grooved floor board

For better installation, the sheet pile board of the floor has a groove along the entire length on one side, on the other - a spike. When calculating the volume of one board, its length, height and net width are taken into account, that is, the width without taking into account the protruding spike. For example, the size of the board shown in the figure below is 28x90 mm.

Grooved floor board

With a board length of 6 meters, its volume will be:

V = 0.09 m * 0.028 m * 6 m = 0.01512 m³

Quantity in 1 cube:

5. How many wooden lining in 1 cube

By design, the lining remotely resembles a sheet pile floor. It also has a groove-thorn connection, ventilation grooves, but the front side of the lining can have bevels, roundings and even a convex surface, imitating a beam.

For the calculation, the “net” width is used, that is, the size without taking into account the spike, the maximum value in the section of the board is taken as the height.

Types of lining with a good example of measuring the width and height of the board

The most common lining size is 100x14. With a board length of 6 meters, the number of lining in one cube will be at least 119 pieces:

The volume of one board:

V = 0.1 m * 0.014 m * 6 m = 0.0084 m³

Quantity in 1 cube:

What else to consider when counting lumber

One of the nuances in the production of lumber is their technological length, that is, the declared six-meter board in practice turns out to be 5-10 cm longer. This deviation is called technological and is not taken into account when calculating the linear meters of the board. The seller in no case has the right to add them to the total length of the board.

When buying a beam of a certain section, it is important to measure the parameters during acceptance or loading, since the slightest deviation of even 1 cm leads to huge losses, especially with large purchase volumes.

In addition to volume, it is important to remember the weight of the purchased material, which depends on the density of the material and humidity.

An example of calculating the weight of a beam based on the known density of a tree (for material of different moisture content, the corresponding values ​​\u200b\u200bmust be substituted instead of 860)

Tables for quick calculation of the volume of timber

Below are cheat sheets to quickly find out how much timber is in a cube - the table contains not only the quantitative values ​​​​of material units in a cubic meter, but also the volumetric values ​​\u200b\u200bof bars of different sections. For example, a table will show how many boards are in a cube - a board or a beam will be 6 meters or 3 meters long.

1. How much in a cubic meter of timber 3 meters long

How many pieces in a cubic meter Volume of one piece, m³

2. How much in a cubic meter of timber 6 meters long

Height, width and length of the beam, mm

How many pieces in a cubic meter

Volume of one piece, m³

If you need to find, for example, how many beams 100x100 in a cube, then in the table we are looking for a board right size and we see the result - at least 16.67 pieces, and the volume of one beam 6 meters long is 0.06 m³.

Features of lumber storage

For building a house made of wood, it is important to properly store the material so that its moisture content is within 12%, if the humidity is higher, then the shrinkage of the building will be slower.

Here are a few rules to remember when storing lumber:

    The storage area must be level and dry.

    To prevent the ingress of moisture from the surface to the site, pallets are laid under the first layer of material, which can be replaced with scraps of boards or sleepers.

    The distance between single products should be maintained within at least 2 cm, for better air circulation.

    After 1-2 rows, crossbars are placed across the length, which can be all the same trimmings of boards.

    If it is not possible to build a canopy over the storage area to prevent atmospheric precipitation, the stacks are covered with a film, excluding wrapping the ends, so as not to create a greenhouse effect inside.

Wood stacked for storage

Conclusion

Knowing the rules for calculating the required volume of building materials will help save time and money, or just make sure the builder is honest. Therefore, if there are no skills to quickly translate one value into another, then when discussing the required amount of building materials, you must keep at least a cheat sheet in the form of a cubic table.
