Question

The ratio of the lengths of corresponding parts in two similar solids is 5:1,

Answer 1

The ratio of the surface areas of two similar solids can be computed by squaring the given ratio of the corresponding sides. For this given,
                                r = (5:1)^1
                               r = 25:1

Thus, the ratio of the surface areas of the similar solids is 25:1. 

Answer 2

25:1 on apex
