Volume of pyramid(V) = [tex]\frac{1}{3}bh[/tex]
where 'b' is the base area and 'h' is the height.
We have to determine the formula for height 'h'.
[tex]V = \frac{1}{3}bh[/tex]
Multiplying by '3' on both the sides of the equation.
[tex]3V = bh[/tex]
[tex]h = \frac{3V}{b}[/tex]
So, the formula for height 'h' of pyramid is [tex]h = \frac{3V}{b}[/tex].
