Determine the base of right triangle by using pythagoras theorem.

$\begin{gathered} b=\sqrt[]{(15.7)^2-(8.5)^2} \\ =\sqrt[]{174.24} \\ =13.2 \end{gathered}$

Determine the area of base of figure.

$\begin{gathered} A=\frac{1}{2}\cdot13.2\cdot8.5 \\ =56.1 \end{gathered}$

Determine the volume of the figure.

$\begin{gathered} V=A\cdot6.2 \\ =56.1\cdot6.2 \\ =347.82 \end{gathered}$

So volume of the figure is 347.82 yards square.
