1

If the amount of the physical body (container, building) is known, but is set in the off-system units, just multiply it by the appropriate factor.For example, to find a cubic meter, knowing the number of liters or cubic decimeter, multiply the number of liters per one-thousandth (or divide by a thousand).

2

If the amount specified in cubic centimeters, then multiply it by one millionth (0.000001).If the volume is measured in cubic millimeters, then trans
fer to cubic meters multiply that number by one billionth (0,000000001)

Example: find the number of cubic meters of domestic gas contained in the standard "propane" balloon.

Solution: conventional cylinder volume is 50 liters.Multiply this number by 0.001 - 0.05 m³ get.

Answer: The amount of gas cylinder - 0.05 cubic meters.

Note.Bottled gas is liquefied and under great pressure, so it is actually a lot more volume.

If you know the weight, then to find the number of cubic meters, multiply the mass density.The mass shall be expressed in kilograms, and the density in kg / m³.The result in this case will in cubic meters.The density of a substance can be found in the corresponding handbooks, or measure yourself.Note that the density of water is 1,000 kilograms per cubic meter.Approximately equal to the same value, and the density used in practice many fluids.

5

In practice, often find the number of cubic meters of helping shape of the object (capacity building).For example, if the body is a rectangular parallelepiped (standard room, a box bar), its volume is the product of the length, width and height (thickness) of the subject.

6

If a base object has a more complicated form, but constant height, then multiply the area of the base and the height.For example, for a cylinder area of the base will be equal to "Pi", "er" square (πr²), where r - the radius of the circle of the underlying.
