Cubic meters are calculated by finding the volume of an object. Wolfram MathWorld lists 15 volume formulae that aid in calculating an object's volume.
- Understand the relationship between volume and cubic meters
The volume of a solid body is the amount of space it occupies, and cubic meters represent volume in the metric system. Therefore, calculating the volume of an object is equivalent to calculating how many cubic meters it contains.
- Identify which volume formula is needed
To calculate cubic meters, identify which object is involved, and select the appropriate volume formula necessary to make the calculation.
- Calculate the volume
The number of cubic meters contained in a box is calculated by multiplying the length times the width times the height. If the width is 5 meters, the length is 6 meters and the height is 3 meters, the volume is 90 cubic meters. If the dimensions of the box are given in feet, these dimensions must be converted to meters; otherwise, the resulting volume is not in cubic meters.
