If I were to have 2 cones:
One with a surface area of 60cm^2 and a larger one at 135cm^2.
If the smaller cone had a height of 15cm how is the height of the larger cone calculated. I understand that you need a ratio but not sure how to arrive at a final answer.
(I posted another similarity question recently but not sure if having surface area changes things.)

the length scale factor is the square root of the area scale factor
