find the volume of the pyramid. in this case the base is a rectangle.

A
Given the figure in the attached image.
Recall that the volume of a Pyramid can be calculated using the formula;
[tex]V=\frac{lwh}{3}[/tex]Given in the figure;
[tex]\begin{gathered} l=12\text{ ft} \\ w=4\text{ ft} \\ h=10\text{ ft} \end{gathered}[/tex]Substituting the given values;
[tex]\begin{gathered} V=\frac{12\times4\times10}{3}=\frac{480}{3} \\ V=160ft^3 \end{gathered}[/tex]Therefore, the volume of the Pyramid is;
[tex]160ft^3[/tex]
