Meter cubed, cubic meter or cubic meter - standard unit of measure of volume. The volume of rooms and also a consumption of water and gas is calculated in these units. The amount of some building materials, for example, of boards is quite often specified in them. Also transfer other, stand-alone units of measure of volume to cubic meters - liters, cubic decimeters and centimeters.
It is required to you
- - calculator;
- - table of density of substances;
- - computer.
Instruction
1. To calculate the number of cubic meters if volume is known, but is set in submultiple, multiple or stand-alone units, then increase it by the necessary coefficient. For example, to calculate the number of meters cubed for cubic decimeters (liters), increase their quantity by 0.001. For transfer to cubic meters of centimeters and millimeters cubic increase their quantity by 0.000001 and 0.000000001, respectively.
2. Example: calculate how many cubic meters of water contain in one bucket. Decision: the volume of a usual bucket is 10 liters. Increase this number by one thousand: 10 * 0.001 = 0.01 m?. Answer: water volume in a bucket – 0.01 cubic meters.
3. If body weight is set, then to calculate the number of meters cubed, increase it by density. Previously transfer weight to kilograms, and density - to kg/m?. It is easy to find density of substance in the Internet or in the corresponding reference books. If the name of substance is unknown or the body consists of mix (alloy) of several substances in an unknown proportion, then measure density independently. If the low-concentrated solutions appear in a task, then the equal density of water can accept their density - 1000 kilograms (ton) on meter cubed.
4. It is often possible to calculate the number of cubic meters and on the basis of a form and the sizes of a body (capacity, the room). For example, if the body is similar to a rectangular parallelepiped that its volume is equal to the work of length, width and height (as height thickness or depth can be meant).
5. If the basis of a body has irregular shape and constant height (prisms and cylinders), then increase the area of the basis of a body by its height. So, for example, for a round cylinder the area of the basis equals? r?, where r is the radius of the circle which is in the cylinder basis.
