My ball sac
A soccer ball with 12 regular hexagons and 20 regular pentagons follows the pattern of a truncated icosahedron. Each hexagon has 6 edges, and each pentagon has 5 edges. Therefore, the total number of edges on the soccer ball can be calculated by multiplying the number of hexagons by 6 and the number of pentagons by 5, then adding these products together. Total edges = (12 hexagons * 6 edges per hexagon) + (20 pentagons * 5 edges per pentagon) Total edges = 72 + 100 Total edges = 172 Therefore, a soccer ball with 12 regular hexagons and 20 regular pentagons has 172 edges.
