Question

The sides of two cubes are in the ratio 2:5, what is the ratio of their volumes?

Answer 1

9514 1404 393

Answer:

8 : 125

Explanation:

The volume is proportional to the cube of the side lengths. Hence, the ratio of volumes is proportional to the cube of the ratio of side lengths.

v1 : v2 = (2 : 5)^3 = 2^3 : 5^3 = 8 : 125
