Question 991555: Use proportions to solve
The faces of two similar cubes have areas in the ratio 9:4. What is the ratio of the lengths of the cubes' edges? What is the ratio of the cubes' volumes?

You can put this solution on YOUR website!
Area scale=9:4--->9%2F4
Then ratio of lenght--->%283%2F2%29%5E2
=3/2
then, the ratio of their volume---->%283%2F2%29%5E3
=27/8
