I heard that you can fold the paper in half dozens of times to the height of Mount Everest, is it tr

It's true, a very simple math problem.

The thickness of a piece of paper is assumed to be one millimeter, and folding it in half once is 1 1 2 millimeters, again it is 2 2 4 millimeters, and again it is 8 millimeters ......It doesn't take a few times, and it's a terrible number......

Fake... No sheet of paper can be folded in half more than 9 times, you can try it yourself!

Yes, it can only be stacked up to 9 times, and it can never exceed this number, no matter how thin and big it is, it can only be 9 times. Because the fiber thickness of paper can only reach that much.

You'll know when you learn the proportional sequence, but no piece of paper can be folded in half more than dozens of times, theoretically possible, but, in practice, it's impossible, unless there is a very large piece of paper!

Hehe, it's not practical, can a piece of paper be folded n times?

No matter how big the paper is, you can't do it.

A piece of paper. No matter how big or small, up to 9 times, you can't fold it, don't believe you try.

The thickness of a piece of paper is assumed to be one millimeter, and folding it in half 20 times is equal to.

1 * 2 to the 20th power of millimeters, it is more than 1000 meters, and then fold 3 times, it is almost the same!

It's so wonderful on the 1st floor... In fact, it is impossible to fold it in half more than 9 times...

To reach that height, you can only figure it out with a pen on paper.

Haha ls is interesting, 1 1 2, 2 2 4, then it is 4 4 8, 8 8 16 ......

From the point of view of calculation, because each time you fold in half, the number of layers of paper will be twice the original, calculated by the average thickness of the general printing paper, folded in half twenty-seven times, and can be reached in the case of the paper is pressed very tightly, exceeding the height of Mount Everest;

But as the previous brothers said, it is generally impossible to find such a large paper, which can also be calculated, assuming that you can find a paper with strong strength and toughness (of course, it cannot be ordinary fiber paper), and the bottom area after demolition is 1m2 (relative to its height, this is already very small), then the plane area of each layer will reach 134217728m2, and the side area is still close (outermost layer height + innermost layer height) 2*4 "Four Sides" * 134217728 "Number of Layers" About 720,000,000,000 m2, or 720,000 square kilometers, in fact, for the case with 134217728 sides, the plane area of the upper and lower floors may need to be much larger, so it is almost impossible to operate.

In the case of assumptions. So let's do the math. Generally, the thickness of the printer paper is to the millimeter.

Here's the millimeter. Multiply by 2 constantlyUsing a calculator, multiplying it 26 times by his height is a meter.

In other words, he only needs to fold in half 26 times, and his height can surpass Mount Everest. Of course, the thickness of the paper is not the same. If there is a difference in thickness, you need to multiply the height by a multiple of it.

If it is not enough for 8848 meters, it will be added once, and if it is more than twice as much as 8848, it will be subtracted again.

It is impossible to do this in reality. Because this violates the law of conservation of matter. Think about it, a piece of paper of one square meter, with a thickness of millimeters.

Then its volume is cubic meters. It is impossible for a cubic meter of paper to change its volume from cubic meters to cubic meters because it was folded in half 26 times, right? This is obviously ridiculous.

In fact, every time you fold in half, the thickness of the paper doubles, and the length or width of the paper is reduced by half. No matter how much you fold a piece of paper, you can't exceed its length. The thickness of the paper keeps increasing, while the length or width keeps decreasing.

When the thickness is greater than or equal to the length or width, it cannot be folded again. You have to turn it in a different direction. Therefore, the theory that the so-called origami height exceeds that of the mountains is always only a hypothesis.

His purpose is to show us how much more terrifying the number of growth is in geometric ways. It's not that we are asked to go to origami.

1. Use folded.

Assuming that it is enough to take k times at most, then the thickness of the first k-1 time fold must be greater than 4000 meters and less than 8848 meters. Calculated in 4000 meters.

In the k-1 time, remember that the top layer is A, the bottom layer is B, and after folding once, A is the middle layer and B is the outer layer. Then b must have the length of b a b layer thickness, which is 4000 + 4000 = 8000 meters! That A length + B length is not less than two B lengths, which is 8000 * 2 = 16000 meters!

It is possible to continue to K-2, K-3,Thinking about it, the length of the paper you end up with can be said to be astronomical!

2. Use scissors.

Since the total volume is constant, it is assumed that the area of the starting paper is 1 square meter (the area of the actual printing paper is much smaller than this value).Since the thickness of the paper is millimeters (i.e. 2*10 (-4) meters), the volume of the paper obtained is 2*10 (-4) cubic meters. Mount Everest is 8000 meters high, assuming that it can be reached, then the area of paper cut is:

2*10 (-4) 8000 = square meters, or square millimeters, and there are 8000 (2*10 (-4)) = 4*10 7 layers! Is this actually cut-out? Can you guarantee to cut 4*10 7 and build them together?

So theoretically yes, but in practice no.

The highest mountain in our country is restored.

It is Mount Everest, 8848 meters. Now I have a piece of paper big enough that its thickness is meters.

Excuse me, how many times do I fold it, yes?

DAO folded into the height of Mount Everest.

Idea: The height of the paper should be greater than or equal to 88,480,000 (Mount Everest) to define the height of the paper, the height of Mount Everest, and the number of times.

The height of Mount Everest is 8,248,000mm, and the thickness of a piece of paper is about, about the number of folds.

For an idler like me, it's good to take it over and over again, and I surpassed it 24 times.

Why is zhi multiplied by 2, can you explain it?

The height of Mount Everest is meters,,2 n=88444300,n=log2(88444300)=,take n=27,A piece of paper with 0.1 millimeter can exceed the height of Mount Everest after folding it 27 times.

Fold it in half once.

Fold it in half twice is.

After folding it in half n times, it is.

Calculate >=8848

2 to the 26th power is equal to 67108864

2 times of 2 times is equal to 134217728 > 88,480,000, so after 27 times of folding, the height exceeds Mount Everest.

Thickness of paper 2 to the 30th power = thickness of paper 1073741824 assuming that the thickness of 1 sheet of paper is millimeters, i.e., meters, then.

1073741824 meters, or more than 100,000 meters, while Mount Everest is less than 10,000 meters.

I don't know exactly how thick the paper is, FYI)

Millimeters = meters.

Theoretically, paper is infinite.

Fold it in half 1 time to become 2 layers, i.e. 2 1

Fold it in half 2 times to become 4 layers, i.e. 2 2

Fold it in half 20 times to become 2 20 layers, that is, 1024x1024 layers, then the thickness is meters.

30 floors each three meters high building, height of 30x3 90 meters, exceeded.

Mount Everest is a meter high.

N 27 starts from folding in half 27 times, and the thickness is more than that of Mount Everest.

107 374 4m＞8 845m．

Answer: After folding a piece of paper with a thickness of a sedan chair as a sock, it can exceed the altitude of Mount Everest (8,845 meters) after folding it in half 30 times in a row
