WHAT YOU NEED TO KNOW:
if the ratio of lengths of sides (or any other measurement) of similar figures on a plane or 3-D solids is ,
the ratio of areas of corresponding surfaces is , andthe ratio of corresponding volumes is ,
and viceversa.

In this case the ratio of atras is

it must be that
and
-->
So
and since
