A parking lot is 200 ft by 300 ft and will receive 3 inches of asphalt. Approximately how many cubic yards of compacted asphalt are needed?

Area = 200 x 300 = 60,000 sq ft. Thickness = 3 in = 0.25 ft. Volume = 60,000 x 0.25 = 15,000 cubic feet. Cubic yards = 15,000 / 27 = about 556. Option d forgets to convert thickness. Option a divides incorrectly. Convert the depth to feet, multiply by the area, then divide by 27 for cubic yards.
