To calculate the amount of materials needed for a concrete pad measuring 16 feet by 12 feet and 4 inches thick, first convert the thickness to feet: 4 inches is approximately 0.33 feet. The volume of the pad is 16 ft × 12 ft × 0.33 ft = 63.84 cubic feet. Generally, a cubic yard of concrete requires about 1 part cement, 2 parts sand, and 3 parts gravel. For this volume, you'll need approximately 2.36 cubic yards of concrete, which translates to about 0.39 cubic yards of cement, 0.78 cubic yards of sand, and 1.17 cubic yards of gravel.
