Note that, if the two solids are similar with a scale factor of x, then the ratio of their areas would be 
and the ratio of their volumes would be 
.
In this case, the ratio of the two similar solids is 3:14. So the ratio of their areas would be
and,
the ratio of their volumes would be
Thus, the answer is 9 : 196 and 27 : 2744.
