The rule of the volume of the pyramid is
[tex]V=\frac{1}{3}\text{base area }\times\text{ height}[/tex]
Since the base of the given figure is a square, then
The base area = 12 x 12 = 144 cm^2
Since the height = 9.1 cm, then
[tex]\begin{gathered} V=\frac{1}{3}\times144\times9.1 \\ V=436.8cm^3 \end{gathered}[/tex]
The volume of the pyramid is 436.8 cm^3
