The total cost is $210 #### Work Step by Step We can find the volume:$V = W \times L \times HV = 12~ft \times 15~ft \times 2~ftV = 360~ft^3$We can convert the volume to units of cubic yards:$V = (360~ft^3)\times (\frac{1~yd^3}{27~ft^3}) = \frac{40}{3}~yd^3$We can calculate the cost:$cost = (\$15.75/yd^3)(\frac{40}{3}~yd^3) = \$210\$
