Calculate the total concrete volume needed for a foundation wall that is 8 inches thick, 8 feet high, and has a total linear length of 240 feet.
Correct Answer
D) 106.7 cubic yards
Volume = 8/12 ft × 8 ft × 240 ft = 1,280 cubic feet ÷ 27 cubic feet per yard = 47.4 cubic yards. Wait, let me recalculate: 0.667 ft × 8 ft × 240 ft = 1,280 cubic feet ÷ 27 = 47.4 cubic yards. The closest answer suggesting a calculation error in the options, but 8/12 × 8 × 240 ÷ 27 = 47.4 cy. There appears to be an error in my options - the correct answer should be approximately 47.4 cubic yards.
