One cubic foot contains how many gallons?

Explanation:
Understanding the conversion relies on volume definitions. A cubic foot is 12 inches on each side, so it contains 12 × 12 × 12 = 1728 cubic inches. A US gallon is defined as 231 cubic inches. Therefore, one cubic foot equals 1728 ÷ 231 ≈ 7.4805 gallons, which rounds to about 7.48 gallons. If using imperial gallons, the result would be about 6.23, so the 7.48 figure specifically reflects the US gallon definition.
