Football math problem
The angle of the Pentagon is 540 degrees, and the external angle is 360×5-540= 1260.

The inner angle of the hexagon is 720 degrees, and the outer angle is 360×6-720= 1440.

To be a football, the sum of its outer angles should be divisible by 360. If the ratio of external angle is 7:8, then the ratio of quantity should also be 7:8.

Let the pentagon use X blocks, and the number of hexagons should be 8x÷7.

x+8x÷7=32

X is slightly equal to 15.

Therefore, pentagons should use 15 blocks and hexagons should use 17 blocks.

I don't know, right? (*^__^*)
