The volume of a cylinder is given by
Let 
and 
The new volume becomes
So, the new volume is 8 times the original volume. In fact, volume scales linearly with the height and quadratically with the radius.

Knowing the amount doubles every 30 days, we'll have to find how many times it'lll double in the 210-day time frame:
210 / 30 = 7
It doubles 7 times. If we were to write a rough, not worked on expresion representing that, knowing the starting population was of 20, we would write:
(((((((20 * 2) * 2) * 2) * 2) * 2) * 2) * 2) = 2560 rabbits
