If it is 4 inches deep/thick, 2 cubic yards.
If it is 6 inches deep/thick, 3 cubic yards.
It depends on the depth required

you can do the math: LXWXD DIVIDED BY 27
A 10-foot round slab at 4 inches requires 1 cubic yard.
9x12 feet at 4 inches deep: 1.3 cubic yards.
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
18x32 feet by 4 inches thick: 7.1 cubic yards. For a 6-inch slab, 10.7 cubic yards.
70 feet! The answer is in the question!
