Question

The volumes of two similar solids have an 125 : 216 ratio. What is the ratio of their side lengths

Answer 1

5:6

Explanation:

To find the ratio of side lengths you need to cube root of the ratio of the volumes. The reason you use the cube root is because you are multiplying 3 things together when you find volume.

`\sqrt[3]{(125)/(216) } =(5)/(6)`

5 : 6
