#### Answer

$h=\dfrac{3V}{b}$

#### Work Step by Step

$\bf{\text{Solution Outline:}}$
To solve the given formula, $
V=\dfrac{1}{3}bh
$ for $
h
,$ use the properties of equality to isolate the variable.
$\bf{\text{Solution Details:}}$
Using the properties of equality to isolate the variable results to
\begin{array}{l}\require{cancel}
3\cdot V=3\cdot\dfrac{1}{3}bh
\\\\
3V=bh
\\\\
\dfrac{3V}{b}=\dfrac{bh}{b}
\\\\
\dfrac{3V}{b}=h
\\\\
h=\dfrac{3V}{b}
.\end{array}
