I remember this "theorem"(?) about how is impossible to fold a paper sheet more that 6 times and this lady glt herself a gigantic thin sheet and folded it like 8 times. OP, fold that and told us how many folds you get.
Mythbusters debunked this, although they used a football field sized sheet and forklifts, but they were able to fold it 11 times. The myth they tested was 7 times being impossible.
Let me help you out with the math here, its pretty difficult. Basically, "impossible to do more than 6" and "7 is impossible" actually mean the same thing! It's crazy how numbers work 😅😅
I don't think your math is right. That's 5x length and 4x width, not 20x length and width. If I was suddenly 20x bigger without changing my proportions, I doubt that would even be a facecloth to me.
