Can anyone help me? Explain how to solve...
Two similar solids have volumes or 27 centimeters cubed and 8 centimeters cubed. Find the ratio of their surface areas.

Volumes vary as the cube of the dimensions and surface areas as the square.
So the ratio of the surface areas is:
(27/8)^(2/3) = 9/4

ratio of volumes is proportionalto the cube of the linear dimensions
27 / 8 = (L1 / L2)^ 3 => L1 / L2 = 3 /2
ratio of surface areas s proportional to the square of the linear dimensions
(L1 / L2)^2 = (3/2)^2 = 9/4
