Thickness after n folds = Original thickness × 2^n
Given that the original thickness of a newspaper is approximately 0.1 mm and the number of folds is 100:
Thickness after 100 folds = 0.1 mm × 2^100
Thickness after 100 folds ≈ 1.2676506 × 10^30 millimeters
Converting to kilometers:
Thickness after 100 folds ≈ 1.2676506 × 10^24 kilometers
Therefore, if a newspaper is folded 100 times, it would have a thickness of approximately 1.2676506 × 10^24 kilometers, which is an incredibly vast distance.
