To calculate the amount of concrete needed for a 14x12 foot pad that is 4 inches deep, first convert the depth to feet: 4 inches is 1/3 of a foot. Then, calculate the volume: 14 ft x 12 ft x (1/3 ft) = 56 cubic feet. Since concrete is often sold by the cubic yard, convert cubic feet to cubic yards by dividing by 27: 56 cubic feet ÷ 27 = approximately 2.07 cubic yards. Therefore, you should buy about 2.1 cubic yards of concrete, accounting for some extra for spillage or over-excavation.

Fourty cubic feet.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
