I assume the volume is $\displaystyle \displaystyle \begin{align*} \frac{4}{3}\pi^3 \end{align*}$. Substitute this as $\displaystyle \displaystyle \begin{align*} V \end{align*}$ into the formula $\displaystyle \displaystyle \begin{align*} S = \pi ^{\frac{1}{3}}\left(6V\right)^{\frac{2}{3}} \end{align*}$ and simplify.
