If the volumes of two cubes are in the ratio 8 to 1, what is the ratio of their side lengths?

Explanation

Given that the volumes of the cubes are in the ratio 8:1, let the side lengths be x and y. Since volume = side³, we have x³ / y³ = 8 / 1. Taking the cube root on both sides, x / y = 2 / 1. Thus, the ratio of their edges is 2:1.
