#### Answer

a) $W=\dfrac{V}{LH}$
b) $H=\dfrac{V}{LW}$

#### Work Step by Step

a) Using the properties of equality, in terms of $
W
,$ the given formula, $
V=LWH
,$ is equivalent to
\begin{array}{l}\require{cancel}
\dfrac{V}{LH}=\dfrac{LWH}{LH}
\\\\
W=\dfrac{V}{LH}
.\end{array}
b) Using the properties of equality, in terms of $
H
,$ the given formula, $
V=LWH
,$ is equivalent to
\begin{array}{l}\require{cancel}
\dfrac{V}{LW}=\dfrac{LWH}{LW}
\\\\
H=\dfrac{V}{LW}
.\end{array}
