A paper sheet of 0.1 mm thickness is taken. Is cut in two and placed one above the other; is a thickness of 0.2 mm.
This roll is cut into two and put prte above the other; is a thickness of 0.4 mm.
The next time the same process takes place, the stack is at a thickness of 0.8 mm.
Assuming the role is of a size that allows for the same procedure 30 times, find the thickness that would have formed the bundle.
