What is the volume of concrete required for a 4 inch thick pad measuring 8 by 20 feet?

Explanation:
Volume for a rectangular pad is found by multiplying length, width, and thickness, with all dimensions in consistent units. Convert the thickness to feet: 4 inches is 4/12 = 1/3 foot. The area of the pad is 8 feet × 20 feet = 160 square feet. Multiply by the thickness: 160 × (1/3) = 160/3 ≈ 53.33 cubic feet. The option 53.28 cubic feet is the closest value to this result, matching the calculation after rounding. If you needed cubic yards instead, it would be about 53.33 ÷ 27 ≈ 1.97 cubic yards. The other numbers come from unit mismatches or different ways of expressing the same volume.
