A cubic foot is equal to 1,728 cubic inches. A cubic inch is equivalent to a volume that is 1 inch long by 1 inch wide by 1 inch deep.
A cubic foot is a unit of measurement that is a part of the U.S. customary system, which is derived from the British imperial system of measurement. It can be used to calculate the amount of space or volume that an object can hold. For instance, the amount of storage space that is in a large shipping container or a semi-tractor trailer can be determined by measuring it in cubic feet.
