What happens if you fold a paper 7 times?
What happens if you fold a paper 7 times?
It would seem quite plain at a glance, but if you take a piece of paper that is only 0.1 mm thick and fold it in half, the new thickness is 0.2 mm. This thickness goes on increasing exponentially, as does the height of the paper. If you fold the same piece of paper 7 times, it would be as thick as 128 sheets of paper.
Can we fold 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 is the world record for most times folding a paper in half?
12 times
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. Read more: Why does paper make noise when crumpled?
What happens when you try to fold a piece of paper in half 8 times?
“The first time you fold it in half, it becomes 150 mm long and 0.1 mm thick. The second fold takes it to 75 mm long and 0.2 mm thick. By the eighth fold (if you can get there), you have a blob of paper 1.25 mm long, but 12.8 mm thick. 30 folds will get you to space, because your paper will be now 100 km high.
Why is folded paper stronger?
Folded paper bears more weight than a flat sheet of paper because of it’s increased thickness. The more thickness of sheet the more load bearing capacity.
What happens if you fold a paper 103 times?
If you fold an A4 sheet of paper 103 times its thickness will roughly be the size of the Universe. Turns out, according to Dr Karl Kruszelnicki, if you do this 103 times the sheet’s thickness will be larger than the observable Universe: 93 billion light-years.
Is it true that if you fold a piece of paper 42 times?
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.
What happens if you fold a piece of paper 50 times?
In fact, if you had a sheet of paper, and folded it in half 50 times, how thick would it be? The answer is about 100 million kilometres, which is about two thirds of the distance between the Sun and the Earth.
What happens if you fold a paper 100 times?
With just over 100 folds, the thickness of the paper would be equal to 93 billion light-years. The reason for this is exponential growth. When you perfectly fold the paper in half, you will double its thickness. Folding the paper in half a third time will get you about the thickness of a nail.
How many times can a piece of paper be folded?
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 when you fold paper 42 times?
If you were to fold a piece of paper in half 42 times, it would reach the moon. Several of those around the table scoffed at this, exclaiming that a single sheet of paper was simply too thin to have its thickness reach any substantial amount after only a few dozen folds.
Can you really only fold piece of paper 7 times?
Yes, absolutely. A piece of paper can, in fact, be folded more than 7 times. It has been done many times in many places all around the world. It’s just that the people who accomplished the feat used a lot of paper! In other words, it was not a piece of paper that you could simply tear from some notebook.
Can you fold piece of 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.
How many times can you fold a piece of paper?
There is no limit to the amount of times one can fold a piece of paper in half if the paper is large enough. However, because the thickness of the paper grows exponentially, a lot of paper would be needed to make more than 8 folds.[1][2][3]
What is fold paper?
Paper Grains. Paper folds best with the grain, parallel to the paper’s grain direction. Sometimes a paper needs to be folded against the grain, which results in a more irregular fold with cracks along the crease. This effect is more noticeable as the paper thickness increases and “scoring” the paper becomes a requirement for a smooth looking fold.
