From Wikipedia, the free encyclopedia
The cubic foot is an Imperial and US customary (non-metric) unit of volume, used in the United States and the United Kingdom. It is defined as the volume of a cube with sides of one foot (0.3048 m) in length. To calculate cubic feet multiply length X width X height.
