Given;
The height of the pyramid is, h = 7 in.
The length of the base is, l = 9 in.
The width of the base is, w = 2 in.
The objective is to find the volume of the rectangular pyramid.
Explanation:
The general formula to find the volume of a rectangular pyramid is,
[tex]V=\frac{l\times h\times w}{3}[/tex]Substitution:
On plugging the given values in the general equation,
[tex]\begin{gathered} V=\frac{9\times7\times2}{3} \\ =\frac{126}{3} \\ =42in^3 \end{gathered}[/tex]Hence, the volume of the rectangular pyramid is 42 cubic inches.
