An A4 paper has the measurements 297 x 210 mm.

If the paper is folded once into an A5 paper it will have the measurements 148,4 x 210 mm.

Question 1: If the A4 paper is folded in the middle 30 times (Not possible in practice, I know, but this is a theoretical problem.), what will the measurements of the resulting paper be?

Question 2: If the A4 paper is folded 9 times, how large is the area of the resulting paper in relation to the original A4?

Question 3: Let's assume that the thickness of the A4 paper is 0,1 mm, how thick will the paper be after 40 folds?

Please, write the answer as clean and pretty as you possibly can.

Thank you in advance, dear geniuses, I suck at math and I want to win the contest.

GTFO
This isn't even REMOTELY difficult math.

Nope you evolved from mud. Even better.

If you think of the paper as a two dimensional plane the math is simple, however paper is three dimensional so it has some width. thus when it folded the height or length is halved while the width is doubled, because total area is preserved. If you folded the paper thirty times over only two axis the width of the ensuing piece would be equal to about 100 million pieces of paper, given that a ream (500) pieces of paper is about two inches thick, the piece you have would be 67 miles long.

Give that as an answer and you just might win

Mud?
Surely you mean to say that he evolved from primordial amino-acids dissolved in lipid-rich coastal sea-water.

This is why I don't understand these faggots, nor would I want to, for I imagine it would be extremely painful.
