The two solids similar and the ratio between the lengths of their edges is 3: 8 whats is the ratio of their surface area

The ratio of their surface area is given by:

                    9:64

We know that if two solids are similar such that the ratio of their sides or edges is given by:

Then the ratio of the surface area of the two solids is given by:

Here we have:

Hence, on squaring both side of the equality we obtain:

   Hence, the ratio of the surface area of two similar solids is:

                          9:64
