Question

1. If the ratio of surface areas of two cubes is 1 : 9, find the ratio of their volumes​

Answer 1

Answer:

Step-by-step explanation:

let side of first cube be 'a' and of second cube be 'b'

surface area of a cube is 4 * side

4a/4b = 1/9

a/b = 1/9

volume of a cube is (side)^3

so a^3/b^3 = (1/9)^3 = 1/729
