Solution:

$\frac{{\mathrm{V}}_{\mathrm{n}}}{{\mathrm{V}}_{\mathrm{a}}}=\frac{\left(4/3\right){\mathrm{\pi r}}_{\mathrm{n}}^{3}}{\left(4/3\right){\mathrm{\pi r}}_{\mathrm{a}}^{3}}=\frac{{\mathrm{r}}_{\mathrm{n}}^{3}}{{\mathrm{r}}_{\mathrm{a}}^{3}}=\frac{{\left[1.25×{10}^{-13}×\left(64{\right)}^{1/3}\right]}^{3}}{{\left({10}^{-8}\right)}^{3}}$
