A toothpick is about 30 long, and a toothpick is about 30 long

At the end of class, the teacher said, "Now let's play an interesting experiment called the magic toothpick." I couldn't help laughing, thinking, just a small toothpick, how capable it is, this time the teacher must be going to make a fool of himself.

If a toothpick is better than my abilities, then what have I become! I saw that the teacher carefully brought a plate of water, as well as a pair of ordinary toothpicks and a few pieces of candy. That wasn't enough, and the teacher found another bar of soap.

I wondered, is it so hard that a toothpick will run in the water? I shook my head and said to myself, "No way!

No way! "What kind of medicine is sold in the gourd, teacher? The teacher seemed to see my suspicion and said with a smile

Come! Come here, everyone! "We watched the teacher's every move intently.

The teacher put a yellow piece of soap into the water with his hand, and we stared at the surface with wide eyes. At this time, someone said, "Did you do something wrong?"

Someone else said, "Teacher, are you deceiving us?" "Someone else said:

Maybe a miracle will happen later! "There was a lot of talk. The teacher only smiled silently, and carefully placed a toothpick on the horizontal surface, only to see that the toothpick was getting farther and farther away from the soap, like two natural enemies.

We watched dumbfounded, and someone said, "I don't believe it, there's sugar!" "I think so:

That sugar hasn't come in handy yet! The teacher was not nervous, but took advantage of the victory to pursue, changed a plate of water, put sugar in the water, took another toothpick, put it in the water, and the toothpick saw that there was sugar to "eat", and immediately leaned over. Oh my God!

It was amazing, and the room fell silent. Friends, some froze with their mouths open, some lay on their stomachs and stared straight at the water, and some scratched their heads and seemed to have a lot ......of questions but couldn't say anything

The specifications of toothpicks are not uniform, and the length of a toothpick is about 5 cm in general, and 10 cm is equivalent to the length of two toothpicks. I have never seen a particularly short (about 3 cm) toothpick, and if there is, it is generally used to fold two toothpicks into two sections. Long toothpicks of 7-8 cm are also available.

The most common toothpick is 5-6 cm.

10 cm is equivalent to 2 toothpicks.

A: Generally speaking, a tooth is about 10 centimeters, which is about the length of a toothpick and a half.

10 cm is approximately equal to the length of two toothpicks.

The length of the 3 toothpicks is 10 cm.

According to the analysis of the question stem, the circumference of the rectangle with a length and width of 3 cm and 2 cm is 10 cm, so the drawing is as follows:

The area of the rectangle is: 2 3 = 6 (square centimeters), A: The area of this rectangle is 6 square centimeters

If there is an x toothpick, then x+1 is divisible by 10,9,8,7,6,5, that is, x+1 is a common multiple of 10,9,8,7,6,5, and it is easy to get the smallest common multiple of spring cherry blossom is 2520

Because there are more than 5,000 toothpicks, the wisdom of the build is 2520*2=5040

So x=5040-1=5039
