Spy story

Question

Thomas and Dick were having a conversation.

D: I used to be a spy

T: No you didn’t.

D: I swear. I once smuggled a highly sensitive document out of a hostile country.

T: Oh, ok. I’ve got to hear this one. How did you get it out of the country?

D: Well, after I had it in my hands, I folded it in quarters and tucked it in a newspaper. I get to the train station and saw that passengers’ items were being searched, so I took it out of the newspaper and folded it in halves twice more so it would fit in a secret pocket in my hat. I dropped everything I was carrying and got past the guards, onto the train. In the train, I heard a commotion. They were looking for me! They knew I had it! I pulled it from my cap, and folded it down very small by folding it in half twice more and jammed it into a crack in the wall. I was almost immediately arrested, but since I had nothing on me I was released after about 2 days. I returned to the train I was on to get the document, hoping that nobody had found my hiding spot. I was in luck! Nobody had found it. I retrieved it and folded it down really small into quarters again to fit it into my super secret wristwatch compartment. I continued on the train home and got out safely.

T: Man, you are sooooo full of crap! I know absolutely that you are lying.

How does Thomas know so absolutely that Dick is lying?

Edited for a punctuation omission.

i thought it was a maximum of 7
For all practical purposes.

Here's why that makes sense.

On your first fold, you're folding a single sheet

On your second fold, 2 sheets

On your third fold, 4 sheets

-----

On your seventh fold, it's 64 sheets.

If you want to try for an eighth fold, it would be 128 sheets.

Try folding pages 1-256 of a book [numbers on both sides remember].

i thought it was a maximum of 7,,,,,,,,,,

doesn't really matter on size of paper at all,,,,,,,,,,

choppa

Yeah it does.

With a small sheet of paper, you might end up with folds making the paper taller than its base, then it would be impossible to fold.

I think I might have another reason why it's impossible though...

Lemme just do the math to find out...

btw, this is all in inches

so lets say there's only one sheet, a normal 8 1/2 by 11 (I think)

8.5 * 11 = 93.5

93.5 * .0032 (I guess that's the thickness of paper.)

That all comes down to...

0.2992 cubic inches if I did everything correctly...

OK I was wrong. I was thinking that the total area of the paper would have been too large to even fit in the watch compartment.

But if I did the math right, the volume of the paper could fit in the watch.

Only if it was folded perfectly without any space in between folds.

In other words, the product of the dimensions stayed the same when it was folded.

So yeah, I was wrong
