Problema Solution
A stack of 256 sheets of paper is one inch thick. A rectangular piece of paper is folded in half downward. Then that paper is folded in half to the right. If this pair of folds could be repeated six more times, how thick (in inches)would the stack of folded paper be?
Answer provided by our tutors
thickness of a single sheet: 1/256 inches
folding the paper in half increases the current thickness by a factor of 2, there would be 2*7 folds executed, so the thickness would become:
(1/256)*2^(2*7) = 64
if you could folder the paper that many times, it would be 64 inches thick
