Recall:

$\overline{){\mathbf{Volume}}{\mathbf{=}}{\mathbf{Area}}{\mathbf{×}}{\mathbf{Thickness}}}$

$\frac{\mathbf{Volume}}{\mathbf{Area}}{\mathbf{=}}\frac{\overline{)\mathbf{Area}}\mathbf{×}\mathbf{Thickness}}{\overline{)\mathbf{Area}}}\phantom{\rule{0ex}{0ex}}\phantom{\rule{0ex}{0ex}}\overline{){\mathbf{Thickness}}{\mathbf{=}}\frac{\mathbf{Volume}}{\mathbf{Area}}}$
