Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

How do you find the volume of an area?

Volume is a measure of capacity and is measure in cubic units. To calculate the volume of a rectangular prism, multiply the area of the base (length × width) times height.

How do I calculate area?

Area is calculated by multiplying the length of a shape by its width. In this case, we could work out the area of this rectangle even if it wasn't on squared paper, just by working out 5cm x 5cm = 25cm² (the shape is not drawn to scale).
