A rectangular shaped fuel tank measures 37-1/2 inches in length, 14 inches in width, and 8-1/4 inches in depth. How many cubic inches are within the tank?

A rectangular shaped fuel tank measures 37-1/2 inches in length, 14 inches in width, and 8-1/4 inches in depth. How many cubic inches are within the tank?

• A. 4331.25
• B. 3000
• C. 5000
• D. 6000

Answer: (A)

Volume of a rectangular tank is found by multiplying its length, width, and depth. Here, 37.5 inches times 14 inches gives 525, and multiplying by the depth of 8.25 inches yields 4331.25 cubic inches. So the tank’s capacity is 4331.25 cubic inches. The other numbers don’t match this exact product of the three dimensions (for reference, 525 × 8 would be 4200, and 5000 or 6000 are simply not equal to 4331.25).
