Adidas, one of the oldest sports wear brand around, has been behind every World Cup ball since 1970. 

The design most soccer fans know best, the Adidas Telstar, which has 12 black pentagons and 20 white hexagons, made its debut at the World Cup Game in Mexico in 1970.

For my gym class, I tried to create a model of the original World Cup ball. I use regular pentagons and regular hexagons having a side of 2 inches.

Do you know the area of each pentagon I use?

How about the area of each hexagon I use?

If I use all 12 pentagons and 20 hexagons to create the World Cup ball, what do you think is the total surface area of the ball?
