White and Black Elf – Football.

White and black are the main colors! Others have seen red in the fog and yellow on the snow! And of course there are many other colors!

Most of the soccer balls we play on the playing field are made of many small black and white blocks of cowhide stitched together. It was found that the black blocks were all pentagonal and the white blocks were hexagonal. Since there are 12 black blocks on the sphere, you can tell you why there are 20 white blocks mathematically.

Analysis: The black blocks are pentagonal and the white blocks are hexagonal, with the five sides of each black skin sewn together with one side of the five white skins. The three sides of each white skin are sewn together with the three black skins.

Therefore, the 12 pieces of black skin on the surface of the closed football are closely connected with several pieces of white skin, and there will be no remaining or missing sides of the white skin and black skin.

If there are x blocks in the white skin, then it has a total of 6x edges, and in the 6x edges, one of the sides is the white skin and the white skin is connected to the white skin, and the other part is the white skin and the black skin are connected, obviously, there are 3x edges connected to the black skin.

Solution: If the white skin has x blocks, then it has 6x edges. The number of edges stitched together with the black skin is 3x.

It has been counted that there are 12 black skins, and each black skin has 5 sides, so the black skin has a total of 5 12 = 60 sides. According to the title, it gets: 3x=60

Solve this equation and get x=20

Therefore, there are a total of 20 pieces of white skin.

It seems to be white-based, give the best ............ in the World Cup missionThank you.

Soccer is played in white and black. Others have seen red in the fog and yellow on the snow! And of course there are many other colors!
