we use the formula of the volume of a rectangular prism
[tex]V=A_B\cdot DBB[/tex]
where DBB is 9 inches
and the AB is the area of the base
[tex]\begin{gathered} A_B=34\times23 \\ A_B=782 \end{gathered}[/tex]
Finally the volume is
[tex]\begin{gathered} V=782\times9 \\ V=7038 \end{gathered}[/tex]
total volume is 7038cubic inches
