A homeowner has decided to fill in his pool. The pool is rectangular and measures 20ft wide, 40ft long, and 5.5ft deep throughout. Each cubic yard of fill dirt cost $12. How much will it cost to fill the pool?

The volume of the pool is


20ft\text{ }*40ft\text{ }*5.5ft=4400ft^3

a cubic foot is 0.037 cubic yards.

thus


4400ft^{3^{}}^{}=4400*0.037=162.8yd^3

but a cubic yard of dirt costs $12, and we need 162.8 cubic yards.

that would cost


12*162.8=\text{ \$1953.6}
