The cubic meter (cubic meter) is the cubic measure taken to use in the international metric system of units of measurements. That is, for determination of number of cubic meters of any material (for example, concrete, gas, wood, etc.) it is necessary to calculate the volume occupied by him. Depending on properties of material and the known basic data it is possible to make it in several ways.
Instruction
1. If the capacity of the capacity containing substance which volume in cubic meters should be calculated then a task measured in liters is known comes down to transfer of liters to cubic meters. The volume equal to one liter occupies space which in the metric system of SI corresponds to one cubic decimeter. The cubic meter contains one thousand cubic decimeters therefore you divide the amount of material measured in liters into one thousand to transfer it to cubic meters. This way in the greatest measure is applicable to fluid substances. For example, if the capacity of a barrel is equal to hundred liters, then filled to the brim with water it will contain 0.1 cubic meter of liquid.
2. If the sizes of a spatial geometrical figure are known, then it is possible to find its volume in cubic meters by means of the formulas corresponding to this figure. For calculation of volume of a cylinder find the work of its height on the squared diameter, and increase the received result by a quarter of number of Pi. For example, if diameter of a log is equal to forty centimeters, and its length is two meters, then volume will be equal in cubic meters to 0.4*2*3.14/4=0.628 m³.
3. If the space filled with the measured substance has the parallelepiped form, then for finding of its volume multiply length, width and height (or depth). For example, the pool filled with water, of fifty, ten wide and one and a half meters in depth will contain 50*10*1.5=750 cubic meters of liquid.
4. If the measured material fills conic space, then increase a cone basis radius square by its height and a third of Pi's number. For example, if sand is filled by a cone with a radius of five meters and two meters high, then its volume will be 5*2*3.14/3≈10.467 cubic meters.
5. For uniform materials there is an opportunity to calculate the number of cubic meters if the lump and density are known. You divide the known weight (it is measured in kg) into density (it is measured in kg/m³) for calculation of volume of material in cubic meters.
