Answer
The total cost is $210
Work Step by Step
We can find the volume:
$V = W \times L \times H$
$V = 12~ft \times 15~ft \times 2~ft$
$V = 360~ft^3$
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:
$cost = (\$15.75/yd^3)(\frac{40}{3}~yd^3) = \$210$
