If you fold a normal piece of paper in half and then fold that in half and then fold that in half etc and repeat the folding 50 times, How thick is your final result? You can assume that the original piece of paper is 1/1000 of an inch thick.

Let t denote the thickness. If we don't fold the paper, then it's thickness is
1*t=2^0 * t
If we fold the paper once, then the thickness is
2*t=2^1 * t
so if we fold it k times it should be
Now substitute k for the number of times it was folded and t for the thickness. I hope you're aware of how ridiculously large this number is with your given dimensions.

Papper can be only be folded again and again 8 times.
