Homework Help: math

Posted by Stripperella on Sunday, December 17, 2006 at 5:28pm.

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.

Or...you can put this in your google search window:

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