How many gallons are in one cubic foot?

• A. 7.48 gallons
• B. 6.23 gallons
• C. 8.00 gallons
• D. 7.00 gallons

Answer: (A)

Converting volume between units uses the standard sizes: one cubic foot equals 12 × 12 × 12 = 1728 cubic inches, and one U.S. gallon is 231 cubic inches. So the number of gallons in a cubic foot is 1728 ÷ 231 ≈ 7.4805, which rounds to 7.48 gallons. If you were using Imperial gallons, you'd get about 6.23, but in typical U.S. practice, 7.48 gallons is the correct conversion. The other values (8.00 and 7.00) are simply less accurate representations of the actual conversion.
