Yards Deep

How would I figure out how many yards of cement i will need in 260 square feet by 4 inch deep?

( 260 ft² ) ( 1/3 ft ) = 87 ft³

1 cubic yard = 27 cubic feet so

87 cubic feet = 3.2 cubic yards

If this is a math problem, you’re done.
If you’re pouring a slab, make forms for your steps and such and order four yards of concrete; use the extra as you see fit. Good luck!
