Question

Each pair of figures is similar. Use the given information to find the similarity ratio of the smaller figure to the larger figure.

a.
2:5
c.
6:7
b.
5:6
d.
3:4

Answer 1

The ratio of volumes is the cube of the similarity ratio. Hence that ratio is the cube root of the ratio of volumes.
∛(250/432) = ∛(2·5³/(2·6³)) = 5/6

The appropriate choice is
b. 5:6
