Answer
\[B=\frac{3V}{h}\].
Work Step by Step
The provided formula is\[V=\frac{1}{3}Bh\] and now solve the formula for \[B\] by multiplying both the sides by \[\frac{3}{h}\]
\[\begin{align}
& V=\frac{1}{3}Bh \\
& \frac{3}{h}\times V=\frac{{}}{{}}\times \frac{1}{{}}B \\
& B=\frac{3V}{h}
\end{align}\]
The formula \[V=\frac{1}{3}Bh\]is for volume of a pyramid, where \[V=\] volume of the pyramid, \[B=\]area of base of the pyramid, and\[h=\] height of the pyramid.
The formula is\[B=\frac{3V}{h}\].
