The volume of a certain rectangular solid is 8 cm3 8 \text{ cm}^3, its total surface area is 32 cm3 32 \text{ cm}^3, and its three dimensions are in geometric progression. The sums of the lengths in cm of all the edges of this solid is <spanclass=′latex−bold′>(A)</span> 28<spanclass=′latex−bold′>(B)</span> 32<spanclass=′latex−bold′>(C)</span> 36<spanclass=′latex−bold′>(D)</span> 40<spanclass=′latex−bold′>(E)</span> 44 <span class='latex-bold'>(A)</span>\ 28 \qquad <span class='latex-bold'>(B)</span>\ 32 \qquad <span class='latex-bold'>(C)</span>\ 36 \qquad <span class='latex-bold'>(D)</span>\ 40 \qquad <span class='latex-bold'>(E)</span>\ 44
