A rectangle is a two-dimensional shape and therefore does not have a volume. It has an area.
If you are referring to the volume of a rectangular prism (also known as a cuboid), the formula is:
V=length×width×height
Where:
- V is the volume
- length is the measure of the longest side of the base
- width is the measure of the shorter side of the base
- height is the measure of how tall the prism is
So, the formula for the volume of a rectangular prism is V=LWH.
