There is a black-and-white football, ***32 pieces, the black skin is a regular Pentagon and the white skin is a regular hexagon. Use the equation to find out how many pieces of black and white leather there are.
If the black leather is X, the white leather is 32-X.
According to Euler formula, [5x+(32-x) * 6]/3+32-[5x+(32-x) * 6]/2 = 2.
The solution is x= 12.
So the black leather is 12 and the white leather is 20.
