Volume is the amount of space inside a three-dimensional (3-D) shape. It is measured in cubic units, such as cubic feet.

Volume is the amount of space inside a three-dimensional (3-D) shape. It is measured in cubic units, such as cubic feet.

This formula also can be written like this: V = l x w x h

Volume is the amount of space inside a three-dimensional (3-D) shape. It is measured in cubic units, such as cubic feet.

Example: What is the volume of a rectangular prism if l = 5 feet (ft), w = 4 ft, and h = 2 ft?

2 ft

4 ft 5 ft

V

Multiply: 5 x 4 x 2 = 40

The volume is 40 cubic ft.
