Simplify the rational expression: (5a^2*b^2*c^-3)/(2a^3) divided by (15a^3*b^-2*c/(b^-5*c^3)a                  1 / (3a^3*b^2*c^2) b                  1 / (6a^4*b*c) c                  1 / (6a^6*b^2*c^2) d                  1 / (2a^3*b*c)

First determine the shape of the bases: round, square, triangular, hexagonal, or something else. Find the formula for the cylinder or prism that matches the shape. Then measure the bases to get the numbers needed for the formulae-- so you can compute the areas of the base times height. Plug in the numbers, compute and compare the results.
