Given
[tex]V=\frac{1}{4}\times B\times h[/tex]Solution
[tex]\begin{gathered} V=\frac{1}{4}\times B\times h \\ \text{Multiple both sides }by\text{ 4} \\ 4\times V=4\times\frac{1}{4}\times B\times h \\ \\ 4V=Bh \\ \text{Divide both sides by B} \\ \frac{4V}{B}=\frac{Bh}{B} \\ \\ h=\frac{4V}{B} \end{gathered}[/tex]
