A rectangular shaped fuel tank measures 27-1/2 inches in length, 3/4 foot in width, and 8-1/4 inches in depth. How many gallons are within the tank?

• A. 8.83
• B. 7.5
• C. 9.5
• D. 10.0

Answer: (A)

You measure volume by multiplying the dimensions of a rectangular tank: length times width times depth. To use a consistent unit, convert width to inches (3/4 foot equals 9 inches). So the volume in cubic inches is 27.5 × 9 × 8.25 = 2041.875 cubic inches. To convert cubic inches to gallons, use 1 gallon = 231 cubic inches. Therefore, gallons = 2041.875 / 231 ≈ 8.84 gallons. That rounds to about 8.83 gallons, which matches the given answer.
