concrete can be purchased cubic yard. How much will it cost to pour a slab 17 feet by 17 feet by 2 inches for a patio if the concrete costs \$40.00 per cubic yard?

Change 2" to feet, find volume of patio in cubic feet, change to cubic yards, and multiply by \$40.000/cubic yard. Post your work here if you get stuck or if you want us to check your answer.

i have no idea what u said.

Volume is length x width x depth.

You have length and width in feet. Put depth of two inches in feet (2/12 feet).

Volume =17 x 17 x 2/12

That is the volume in cubic feet. For the volume in cubic yards, divide by 27.

The cost? now multiply by 40.

17*17*2/12 * 1/27 *40 dollars
