# How Many Times Can You Fold A4 Paper?

## How many times can you fold a4 paper in half?

It is commonly claimed that you cannot fold a piece of paper in half more than seven times.

That may be true for a standard piece of paper of A4 dimensions, but according to US teenage (at the time) mathematician Britney Gallivan the maximum number of folds is in fact dependent on the initial size of the sheet..

## How many times can you fold a standard piece of paper?

The commonly accepted wisdom is that you can’t fold a single sheet of paper in half more than seven times. The problem with folding paper in half multiple times is that the paper’s surface area decreases by half with each fold.

## What happens if you fold a piece of paper 400 times?

What will happen if we fold a 1 mm paper 400 times? … A paper will torn as it is not very elastic. On folding it so many times, it’s thickness is gonna be astronomical. It is not possible to get a paper huge enough so that it can be folded so many times.

## Is it true that if you fold a piece of paper 42 times?

If you could fold a piece of paper 42 times, the thickness would be enough to reach the moon. A standard sheet of paper is about 0.1 mm so 42 folds would give us this: 0.1 * 2 42 = 439,804,651,110 mm. This, of course, could not be done with a standard sheet of paper because of its physical limits.

## Why does Paper explode after 7 folds?

“Why does paper explode when under extreme pressure?” Well, the main reason is that paper is made of cellulose (which is derived from wood), and wood explodes under extreme pressure. From a structural standpoint, paper is just a bunch of thin wood with words on it.

## How many times can you fold a piece of paper until it reaches the moon?

Given a paper large enough—and enough energy—you can fold it as many times as you want . Problem: If you fold it 103 times (only if you could ) , the thickness of your paper will be larger than the observable Universe: 93 billion light-years. Yes,on folding the paper 42 times ,it would reach the moon.

## How long would a piece of paper be if you folded it 100 times?

If you have a large piece of paper and enough power to fold it, you can halve it many times. But oops, there is a problem: if you fold the paper 103 times, the thickness of this ream of paper will exceed the known size of a universe, which is 93 billion light-years.

## What happens if you fold a paper 100 times?

The myth: You can’t fold a paper in half more than eight times. * The reality: Given a paper large enough—and enough energy—you can fold it as many times as you want. The problem: If you fold it 103 times, the thickness of your paper will be larger than the observable Universe: 93 billion light-years. Seriously.

## Why can’t we fold paper 7 times?

There’s an old myth that you can’t fold a single sheet of paper in half more than seven times, because each time you make a fold, the thickness of the paper doubles, and soon requires impossible amounts of energy to finish the crease.

## How thick would a piece of paper be if it was folded 50 times?

Each time you fold a piece of paper, you double the thickness. So, a paper that has been folded 50 times will be as thick as 2 50 pieces of paper (About 1 quadrillion, or 1,000,000,000,000,000). Paper folding is exponential.

## What if we fold a paper 50 times?

Each time you fold a piece of paper, it gets twice as thick. … If a piece of paper is . 1 mm thick, folding it 50 times makes it 2^50 times thicker, and you get 112 million km (80 million miles), or . 75 AU (the distance from the earth to the sun).

## How thick is a piece of paper in thousandths?

Calipe refers to the thickness of a paper in thousandths of an inch. To be approved to ship via USPS, your paper must be at least 3.5 inches high x 5 inches long x 0.007 inches thick.

## Why does folding paper make it stronger?

Paper is very weak under compression and is somewhat stronger under tension (i.e., it collapses when you push the ends together but it doesn’t pull apart easily). … By folding or rolling the paper, you create a “thickness” which allows the paper to reinforce itself and not collapse so easily.

## What is the thickness of a4 paper?

16.54 in. A4 210 mm 297 mm 8.27 in. 11.69 in.

## How many miles is it to the moon?
