A 12ft x 25ft x 6in slab measures 12 x 25 x 0.5 = 150 cubic feet. There are 3 x 3 x 3 = 27 cubic feet in one cubic yard. Therefore 150 cu ft = 150/27 = 5.56 cubic yards.

3.95 cubic yards of cement are needed for a slab that size.
625 times 0.5 = 312.5 cubic feet will be needed
you can do the math: LXWXD DIVIDED BY 27
A 10-foot round slab at 4 inches requires 1 cubic yard.
