A tank with internal dimensions of 40 feet X 20 feet X 12 feet is pressed with fuel oil weighing 54 pounds per cubic foot. What is the weight, in short tons, of the liquid?

Correct Answer: Option B — 259.2 short tons

Volume is calculated as 40 x 20 x 12 = 9,600 cubic feet. Multiplying by the density of 54 lbs/cu ft yields 518,400 pounds. Dividing by 2,000 pounds per short ton results in exactly 259.2 short tons.
