The area of a pyramid is given by:
[tex]V=\frac{1}{3}\cdot l\cdot w\cdot h[/tex]
where:
[tex]\begin{gathered} l=15 \\ w=10 \\ h=12 \end{gathered}[/tex]
So:
[tex]\begin{gathered} V=\frac{1}{3}\cdot(15)\cdot(10)\cdot(12) \\ V=\frac{1}{3}\cdot1800 \\ V=600_{\text{ }}cubic_{\text{ }}units \end{gathered}[/tex]
