Question

What is the ratio for the surface Areas of the rectangular prism’s shown below given that they are similar and that the ratio of the edge Lengths is 8:5

Answer 1

`\frac{ {8}^(2) }{ {5}^(2) } = (64)/(25)`

B) 64:25

Explanation:

Ratio of Lengths = a/b

Ratio of Areas = a^2/b^2

Ratio of Volumes = a^3/b^3
