Question

The total surface area of the smaller bin is 408.5 square feet. What is the surface area of the larger bin?

340.4 square feet

705.8 square feet

490.2 square feet

588.2 square feet

Answer 1

Assuming they are similar figures:
If the ratio of their dimensions is 5/6 (smaller/larger), then the ratio of their surface areas will be 5^2 / 6^2, or 25/36.

Using this information, you should be able to set up a proportion to solve for the surface area.
(S.A. of smaller)/(S.A. of larger) = ratio of S.A.
