Advice 1: How to calculate the volume of wood

When purchasing timber, the buyer usually faces a problem of translation. Quite often the wood is sold in cubic metres, for the same unit of measure is set, and the instructions for the production of various products usually the number of materials is specified in linear metres. If you do not want to overpay lumber, and learn to count correctly.

Instruction
1
Determine which kind of lumber you need. Consider them in different ways. The cost is influenced by some other factors – the species of wood, degree of processing (boards can be edged or unedged), grade, length. Short boards are cheaper long. The lumber has its own standards before purchase is very helpful to read them. Do not hesitate to ask the shop price list.
2
One of the types of wood, which often requires gardeners – slab. It should be graded depending on the length. One group includes business slab over a length of 2 m, the other – in short this length.
3
Lay the slabs in a pile. Fold it so that the thick part of one of the trunk side by side on both sides comly others. The planks are stacked in pairs, adjoining flat portions. Convex surface "look" up and down. The stack must be very dense and have right angles.
4
Measure the length, width and height of the pile. For lumber there are two types of cubic meters – stacked and tight. Dense represents, for example, a cube made from a single piece of wood. Thus it is possible to measure, for example, the amount of smooth boards. In the case of drum you are dealing with a stacked cubic meter.
5
The ratio of lumber in stock and dense cubic yards, it is very important for cost calculation. So the buyer had to pay for the share meter as dense, has a special conversion factors that ranged from 0.43 for long debarked slabs to 0.56 for a short debarked.
6
The volume of all the other lumber can be determined by direct measurements of each Board or each log. If the boards are piled in a dense rectangular stack, you measure its length, width and height. Multiplying these parameters, you will receive a volume. To log important parameters are the length and diameter of the saw cut. Cut down barrel with some degree of approximation can be taken as a cylinder. The basis is provided by the upper end. Some features of the calculation of the volume of unedged boards. For the width is taken the arithmetic average of both plasma (i.e. flat surfaces).

Advice 2 : How to calculate the volume of a cube

Calculate the volume of a cube may be necessary not only in solving mathematical problems. For example, you need to know how many bricks in a package of the cubic form or how much liquid or dry ingredients will fit into a container. For this course, you will need to clear up a few options, but first, you need to calculate the volume of a cube.

Remember what CC It is a right hexahedron — geometric solid, each face of which represents a square. Since all sides of a cube are the same — and faces his equal, as were the ribs. That is, to determine the volume you need to know the size of only one face.
2
Remember, what is the volume of the parallelepiped. It is equal to the area of the base multiplied by the height. But the cube length, width and height are equal. The cube can be put on any face, all the same, the footprint will be the same as in the original position. Indicate the edge of the cube as well. Find the area of the base. It is equal to the product of the length by the width, that is, S=a2..
3
Calculate the volume by multiplying the area of the base A2 at the height which in this case is also equal. Accordingly, the volume V is equal to the size of the edge of the cubeerected in the third degree. V=a3.
4
If you need to calculate the amount of a substance, which is supposed to fill a container of cubic shape, it is necessary to know the density of the substance. This number will be equal to the density multiplied by the volume of the cube. And in order to calculate, for example, the number of bricks in a container of cubic shape, it is necessary to calculate the volume of each brick, then divide the volume of the container to the volume of the brick.
Note
In some cases it is necessary to find the volume and the area of the walls - for example, when calculating the number of glass for the aquarium. Since all faces of a cube are the same, the square sum of the areas of the 6 faces, that is expressed by the formula S=6a2
Useful advice
Try practical measurements as accurate as possible. You can use a ruler, tape measure, bar-compass. Importantly, the division met the standards.

Advice 3 : How to calculate the number of boards

If you started building in the country, in the house or on the plot, you will need to calculate the required number of building materials. When we calculate the quantity of timber or boards, individually to determine their required number is not so difficult. However, the price in the markets or in specialized selling organizations, usually specified per cubic meter. As a novice Builder to calculate the number of boards in a cubic meter?
How to calculate the number of boards
You will need
  • Paper, pencil, calculator
Instruction
1
Let's say you have calculated that for the construction you need 40 boards with a length of 6 m, width 150 mm, thickness 40 mm. Put all these values are in meters and multiply:
40х6х0,15х0,04=1,44, where 40 is the number of boards; 6 – length of the Board; 0,15 – Board width; 0,04 – Board thickness.
Finally got a 1.44 cubic meters, nearly half a cubic meter.
2
The same method calculate how many boards will be in one cubic meter: divide the cubic meter by the volume of one Board. For our example, in which the Board thickness of 40 mm, a width of 150 mm and a length of 6 m, the calculation would be:
1/0,04/0,15/6=27,7777.
This means that in one cubic meter can hold about 28 of the required boards.
3
The above calculation is suitable for lumber and trim boards. To calculate the number of required lining, unedged boards and other lumber will have a little differently – you will need a table to calculate the cubic content of timber.
Note
Consider the calculations that if you leave lumber sellers often try to round values square footage is not in your favor.

Advice 4 : How to calculate cubic meter of wood

In everyday life and technology wood called the internal part of the tree underneath the bark. For wood , the main and most important are the following properties: texture (figure fibers of wood), strength, hardness, deformability (the ability derivativesa), specific viscosity, thermal conductivity, sound conductivity.

Wood is a raw material for the production of more than twenty thousand products and articles. Methods of processing of wood raw material divided into three groups: mechanical, chemical-mechanical and chemical. Mechanical processing of wood is to change its shape by sawing, planing, milling, peeling,drilling, cleaving. As a result of mechanical processing receive a variety of consumer goods and industrial products. The value of various species of wood is their strength, durability and uniqueness of the figure. This wood is used to make beautiful furniture, flooring, doors, and various interior items that are considered elite, given the initial high cost and the size of the effort spent on processing it. In Russia, the most common the following species: oak, cherry, beech, pear, rosewood, mahogany, walnut, maple.

Board — lumber thickness up to 100 mm and a width exceeding twice the thickness. Boards are made of logs or timbers. Used in construction, furniture industry, manufacturing etc. depending on propylesoste edges are of the following types of boards: edged ( skromnoi both sides), one-way cut (with the edge on one side) and edging. When the sale of the timber, of course, have to measure them. Indeed, in contrast to other types of products do not sell them either individually or by weight, and in cubic metres. Volume of sawn softwood and hardwood is defined in two ways. You need to measure par and calculate its volume, the volume is calculated by the formula V= length X(times) width X(times) the thickness. So you will get the volume of one Board, now count all the plates, multiply the volume of one Board on a number of boards and you will get the volume you imported lumber.
3
Still the amount of wood you can calculate using the so-called kubaturnykh (GOST 5306-83), which is designed to calculate the amount of edging saw-timbers of coniferous and deciduous species. In subatomic (standard) a table of the volume of one meter length and table of one piece of lumber. Based on these, and determine the purchase price. For example, we need to find the volume of 70 edging boards thickness 22 mm, width 125 mm and length 4.5 m. For this table, find the thickness of sawn timber 22 mm and at the intersection of horizontal column where you specify the width of 125 mm, and vertical columns, wherein said length of 4.5 m, find the volume 0,01238 m3. Then by multiplying the volume by the number of timbers in the party will get the desired volume in m3: 0,01238 m3 X 70=0,8666 m3. For reference will answer that in four-axle gondola is about 55-60 m3 of edged softwood lumber.
Note
Recalculate your results 2 time to avoid errors. Be careful with wood, don't get yourself a splinter, it is better to use gloves.
