How to Calculate Volume

Volume is the measure of three-dimensional space an object occupies, and it’s measured in cubic units, such as cubic feet or cubic meters.

You can use a basic length × width × height formula to calculate the volume of a box.

V = l × w × h

Therefore, the volume of a rectangular box (rectangular prism) is equal to its length times its height times its width, all in the same unit.

You can use our volume calculator to calculate the volume of other shapes.
