A concrete foundation for a building has the shape of a rectangular prism. The foundation is 17 yards long, 16 yards wide, and 3yards high. If concrete costs $4 per cubic yard, how much did the concrete cost for the foundation?

WRONG AGAIN!!!

volume = (17 yards)(16 yards)(3 yards) = 816 yards^3
cost = $4(816) = $ 3264

The concrete cost for the foundation would be $1568.
