Here's the equation that governs growth.
At t=0, N=1, 1 cell exists.
At t=4 minutes, N=2, 2 cells exist.
N(t)=2^((1/4)t) where the variable, t, is measured in minutes.
3 hours = 3(60) minutes = 180 minutes.
N(180)=2^((1/4)180)
N(180)=2^(45)
N=35184372088832
The number's so big, let's switch to scientific notation.
N=3.52x10^(13)
