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.

Figure 1 A common type of soccer ball, covered with 12 pentagons and 20 hexagons.
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.
What size are the hexagons on a soccer ball?
The hexagon has a two inch diameter.
Why does a soccer ball have 32 panels?
The ball’s classic construction with 32 panels means that the ball meets resistance at a later point in its trajectory through the air, thus retaining a steady, high speed over a longer period of time. This provides a stable and more predictable flight – highly valued by all soccer players.

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.
What is the shape of a soccer ball called?
In particular, the standard soccer ball is a truncated icosahedron. After truncation, the 20 triangular faces of the icosahedron become hexagons; the 12 vertices, as shown here, turn into pentagons.
