1 ft³ equals how many gallons?

Explanation:
A cubic foot is a volume of 1 ft by 1 ft by 1 ft. In cubic inches, that’s 12 × 12 × 12 = 1728 cubic inches. A US gallon equals 231 cubic inches, so 1728 ÷ 231 ≈ 7.48. Therefore, 1 cubic foot is about 7.48 US gallons. (Imperial gallons are different, around 6.23 per cubic foot.)
