The volume of the triangular prism on top is:

[tex]\begin{gathered} V1=(\frac{b\cdot h}{2})\cdot l \\ where\colon \\ b=20ft \\ h=25ft \\ l=22ft \\ V1=\frac{20\cdot25}{2}\cdot22 \\ V1=5500ft^3 \end{gathered}[/tex]

The volume of the rectangular prism underneath is:

[tex]\begin{gathered} V2=l2\cdot w\cdot h2 \\ where\colon \\ l2=22ft \\ w=20ft \\ h2=10ft \\ so\colon \\ V2=22\cdot20\cdot10 \\ V2=4400ft^3 \end{gathered}[/tex]

Therefore, the total volume will be:

[tex]\begin{gathered} V=V1+V2 \\ V=5500ft^3+4400ft^3 \\ V=9900ft^3 \end{gathered}[/tex]
