What is the weight of 0.5 cubic feet of water in pounds?

• A. 31.2 pounds
• B. 62.4 pounds
• C. 15.6 pounds
• D. 12.4 pounds

Answer: (A)

Weight is found by multiplying density by volume. Water has a density of about 62.4 pounds per cubic foot, so half a cubic foot weighs 62.4 × 0.5 = 31.2 pounds. One cubic foot weighs 62.4 pounds, so half that volume weighs half that weight. This aligns with the given answer.
