Question

the ratio of the lengths of corresponding parts in two similar solids is 5:1. what is the ratio of their surface areas? a. 125:1 b. 10:1 c. 5:1 d. 25:1

Explanation:

Step1: Recall surface area ratio rule

For similar solids, the ratio of surface areas is the square of the ratio of corresponding linear dimensions.

Step2: Square the given length ratio

Given length ratio = $5:1$, so surface area ratio = $5^2:1^2 = 25:1$

Answer:

D. 25:1
