Most modern balls have 32 panels of waterproofed leather or plastic: 12 regular pentagons and 20 regular hexagons. Older balls have 18 panels.
Hope this helps!

20 pentagons, 12 hexagons
The shape is "geodesic", as in the geodesic dome of the 1967 World's Fair in Montreal, designed by architect Buckminster Fuller.
As it turns out and was discovered in the 1990s, this is also the third natural form of carbon (along with graphite and diamonds): 60 atoms with vertices arranged in the same way as the corners and edges of the hexagons and pentagons of a football.
It's called a "Fullerene" or a "Buckyball", and occurs in two places: stars that have novaed, and in arced carbon tips (where electricity has jumped between and burned the carbon). It also conducts electricity and is theorized to have applications as tubes in atom-sized computers.

12. A soccer ball is basically a truncated dodecahedron, or a truncated icosahedron. It has 32 panels.
