A shape’s volume is a measure of its total 3-dimensional space. You can use the following simple formulas to help you calculate the volume of shapes like cuboids and prisms.

Part of

The volume of a shape measures the three dimensional (3D) amount of space it takes up. Volume is measured in **cubes**.

A cubic centimetre is the volume within a cube that has sides of length , as shown above. It has a volume of ( cubed).

This cuboid contains cubes. Each cube has a volume of . So the volume of this cuboid is .
