Yards are for measuring length not volume.

Cubic yards required will be as follows:

1 cubic yard = 3 feet x 3 feet x 3 feet = 27 cubic feet

Your concrete pad is 30ft x 40ft x 0.3333ft (4 inches assumed) = 400 cubic feet

400 divided by 27 = 14.8148 cubic yards required

How much sand shingle cement do you need for a concrete pad 16 foot by 12 foot x 4inc thick?

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.


How many yards of concrete does it take to pour a 30 x48 pad 6 inches thick?
