The volume of a rectangular prism is given by the formula
[tex]V=Bh[/tex]where
B is the area of the rectangular base
h is the height of the prism
In this problem
[tex]\begin{gathered} B=(19((9)=171\text{ yd}^2 \\ h=16\text{ yd} \end{gathered}[/tex]substitute
[tex]\begin{gathered} V=171(16) \\ V=2,736\text{ yd}^3 \end{gathered}[/tex]The answer is option C
