The volume of a pyramid can be obtained using the formula
[tex]V=\frac{1}{3}b\cdot h[/tex]According to the statement the base area is 9 squared inches and has a height of 10 in, using this information the volume is:
[tex]\begin{gathered} V=\frac{1}{3}(9)\cdot(10) \\ V=\frac{90}{3} \\ V=30in^3 \end{gathered}[/tex]
