This semester, I met a unit bigger than10 million-1 100 million. I open my Chinese book and count the words on each page. Each page is about 180 words, and the Chinese book * * 185 pages. I calculated with a calculator: 180× 185 = 33300 words. It seems that a Chinese book has about 33,300 words. So how many Chinese books can be compiled with 100 million words? I use a calculator to calculate: 1 0000000 ÷ 33300 ≈ 3003.0003. It turns out that there are about1100 million words in 3003 Chinese books! It's amazing! If we observe carefully and use our brains, we will find more mathematical mysteries!

How big is 100 million

"Let's measure how big 100 million is!" I said. "good!" So my father and I measured the scale of 100 million together.

We thought about it for a long time and still couldn't figure out what to measure. It suddenly occurred to me that we could measure the stairs. So we started to act. Please look at our method!

We first measured the height of a staircase: 17 cm high. Then calculate the height of 10 staircase:17×10 =170cm. Then calculate the height of section 100:170×10 =1700 cm. Finally, figure out how high 10 thousand knots and 100 million knots are. Wow! 100 million flights of stairs 17000000 meters, too high, even higher than Mount Everest! I was stunned.

How big is 100 million

1 100 million is a big number. A dollar coin is very thin. How thick are 100 million one-dollar coins? I began to study it.

I first took the coin of 10 and measured it with a ruler: 1.8 cm, which can be estimated as 2 cm. 100 coin? I think: the forward speed of decimeter and centimeter is 10, so the coin of 10 is about 20 cm, which is 2 decimeter. I continued to calculate and finally got the answer: 20 kilometers.

100 million is too big. 100 million coins are 20 kilometers high. 100 million is really big.

How thick is a hundred million pieces of paper?

Today, I am reviewing math. Looking at it, I saw the number sequence table on the fourth page of the book, and then I saw one billion bits. I turned it over and over again, turning to page 2 1, and saw 6 1 billion, with eight zeros after the number. Then I thought: How big is the figure of 100 million?

Want to know how thick 100 million pieces of paper are stacked? I brought a math book, which consists of about sixty-five pieces of paper. I will use it for oral arithmetic training. It consists of about forty pieces of paper. I put my math book and oral arithmetic training together and measured it with a ruler. Its thickness is about one centimeter. I use the results just now to calculate the thickness of 1000 sheets of paper. If there is a zero difference between 1000 sheets of paper and1000 sheets of paper, there should be a zero behind one centimeter, that is, ten centimeters, that is, one decimeter. I counted them one by one, and the final result was ten kilometers. Think of Mount Qomolangma, the world's highest peak, which is only over 8,800 meters high, and 100 million pieces of paper are higher than Mount Qomolangma.
