When you fold it in half again, then what you have left is 4 times as thick as what you started with. Then 8, 16,32..so on. Therefore, the thickness of paper folded 42 times is (2^42)(0.05)That works out to about 219,902km thick.

Similarly one may ask, can you fold a paper more than 7 times?

As you can see, paper can be folded more than seven times. You just need to use bigger and bigger pieces of paper to increase the number of folds possible. It can be fun to play with the mathematics of paper folding to see how thickness increases exponentially with each fold.

What will happen if you tear a piece of paper?

Why can't we fold a paper more than 8 times?

It's commonly accepted that you cannot fold a single sheet of paper in half more than 7 times, no matter what paper finish, size, or basis weight you're using, for two main reasons: Every time you fold your sheet, you reduce your total surface area by half, so eventually you simply run out of surface area to fold.

Why can't we fold paper 7 times?

It's commonly accepted that you cannot fold a single sheet of paper in half more than 7 times, no matter what paper finish, size, or basis weight you're using, for two main reasons: Every time you fold your sheet, you reduce your total surface area by half, so eventually you simply run out of surface area to fold.

What if we fold a paper 50 times?

Exponential growth. 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 2⁵⁰ pieces of paper (About 1 quadrillion, or 1,000,000,000,000,000).

Can you fold a piece of paper 10 times?

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.

What is the most times a paper can be folded?

The current world paper-folding record belongs to California high school student Britney Gallivan, who in 2002 managed to fold a 1.2km-long piece of tissue paper 12 times.

Why is folded paper 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 world record for folding an A4 piece of paper?

To do this, however, involves an exponential increase of the necessary energy to fold the paper, which wasn't computed. The current record for the most times a standard A4 has been folded in half is twelve, and was set by Britney Gallivan more than 10 years ago when she was only a high school student.
