Twelve pentagons and 20 hexagons form a figure known to mathematicians as a truncated icosahedron, to chemists as the buckminsterfullerene molecule—and to nearly everybody else as the standard soccer ball.
Why does a soccer ball has 12 pentagons and 20 hexagons?
When an icosahedron is (partially) truncated at all its 12 vertices then each of 20 triangular faces become a hexagon & each of 12 vertices produces a new petagonal face. Thus a truncated icosahedron has 12 regular pentagons & 20 regular hexagons.

Is a soccer ball a regular polyhedron?
Examined from the perspec- tive of graph theory, the standard soccer ball has three important properties: (1) it is a polyhedron that consists only of pentagons and hexagons; (2) the sides of each pentagon meet only hexagons; and (3) the sides of each hexagon alter- nately meet pentagons and hexagons.
Why do soccer balls have hexagons?
The ball’s pattern of white hexagons with black pentagons made it easily visible on television. An added bonus for players: The black pentagons helped them learn to curve the ball better by being able to track its movement more easily.
