Question

Concrete can be purchased by the cubic yard. How much will it cost to pour a slab that is 17 ft by 17 ft by 2 ft if the concrete costs $40.00 per cubic yard?

Answer 1

1 cubic yd (= 27 cubic ft) of concrete costs $40.00.
The volume the slab is 17*17*2 cubic ft.
So the cost is $40.00 * 17*17*2/27.

Answer 2

Thanks!
