What is the maximum number of times a piece of paper can be folded? Why?

12 times. Theoretically, if the thickness of the paper is zero, it can be folded in half countless times, however, due to the existence of the actual thickness of the paper, this theory does not exist, because the width of the folded paper cannot be less than or equal to the thickness of the paper, that is to say, the width of the paper after folding should be greater than 1mm for a piece of paper with a thickness of 1mm.

Therefore, the maximum number of times a piece of paper can be folded in half is actually a variable, and it depends on the actual thickness and size of the paper. Fold a piece of paper 1 mm in half 100 times, and its thickness can exceed the distance from the Earth to the Moon, is just an unrealistic mathematical reasoning number.

According to the actual calculation, the size of the new board large original paper is 840mm 1188mm (one big open), that is, the size of 16 sheets of A4 paper, if the paper thickness is set to 1mm, the size of its fold 1 time should be 840mm which is the loss of the fold), the actual size of the fold twice is, the size of the fold three times is, that is to say, the actual size after each fold must be subtracted from the thickness loss of the fold, (of course, if it is not folded in half, The size of the paper after four folds should be, theoretically, when the paper is folded to the sixteenth time (excluding the loss of the fold), the size should be, but if the fold loss is calculated, it can only be folded to the twelfth time.

Refers to the common A4 size of ordinary writing paper, and "fold" refers to similar to the usual manual operation of the fold, the total thickness of the paper is 512 times that of a single sheet after folding nine times, that is, the thickness at this time is much greater than the width (the width has become 1/512 of the original), then due to the characteristics of the material mechanics of the "paper" such as bending and elasticity, it cannot be done without breaking (tearing).

As of March 2020, a piece of paper can be folded in half up to 13 times.

In 2011, teachers and students at St. Mark's High School in Texas folded a 10,000-foot-long (nearly 4-kilometer) piece of toilet paper in half 13 times, and in order to complete the experiment, they placed the toilet paper in a corridor of more than 200 meters at the Massachusetts Institute of Technology and folded it collectively for more than four hours. After folding it in half 13 times, the toilet paper reached 8,192 layers.

Depending on the thickness and width of the paper, the thickness of the paper will exceed the width after a certain number of folds. After that, it is no longer possible to fold anymore, and the limit is reached.

Each half fold doubles the thickness of the paper, so that a piece of paper with a thickness of t folds n times is 2 t. At the same time, each fold halves the width, so that after n folds, when the total thickness of the paper is equal to its width, it cannot be folded again.

1. No matter what kind of paper you take out in life, you will not fold it in half more than 9 times.

2. In 2001 (when he was still a high school student), Britney Gallivan proposed a function that allowed him to fold a piece of paper in half 12 times. Previously, it was thought that no matter how big the paper was, it could only be folded in half up to 8 times.

Teachers and students at St. Mark's Middle School in Texas folded a 10,000-foot-long (nearly 4-kilometer) piece of toilet paper in half 13 times. To complete the experiment, they placed toilet paper in a corridor of more than 200 meters at the Massachusetts Institute of Technology and folded it collectively for more than four hours. After folding it in half 13 times, the toilet paper reached 8,192 layers.

Breaking the Guinness Book of World Records.

4. Assuming that the paper is square, the side length is a, and the thickness is h, when it is folded once, the side length remains the same, and the thickness is 2h, when it is folded twice, the length of the folded side is one-half of the original side length, and the thickness becomes 4h, you can launch a formula: the side length is l (2 (, the thickness becomes 2 n*h.

5. Based on this formula, we can conclude that it cannot be folded when n >, so if we fold a piece of paper of 1mm 100 times, we can calculate its thickness as 2 100*, which is the distance between the earth and the sun.

How many times can a piece of paper be folded in half?Can the thinnest millimeter tin foil be used for more than 9 experiments?

No matter how big a piece of paper you have, you won't fold it in half more than 9 times at most. Don't look at the small number, cumulatively, stacking 30 times is equivalent to the height of 10 Everest, amazing!

No matter how thin the paper is, it can only be folded 7 times.

In the same year, teachers and students at St. Mark's Middle School in Texas folded a 10,000-foot (nearly 4-kilometer) piece of toilet paper in half 13 times, and in order to complete the experiment, they placed the toilet paper in a corridor of more than 200 meters at the Massachusetts Institute of Technology and folded it collectively for more than four hours.

3. Assuming that the paper is square, the length of the side of the stove is a, and the thickness is h, when it is folded once, the side length remains the same, and the thickness is 2h, and when it is folded twice, the length of the folding side is one of the two parts of the original side length, and the thickness becomes 4h, and a formula can be introduced: the side length is l (2 (, and the thickness becomes 2 n*h.

4. Based on this formula, we can conclude that n cannot be folded when >, so if we fold a piece of 1mm paper 100 times, we can calculate its thickness as 2 100*, which is the distance between the earth and the sun.
