# Why (I thought) the Euro Ball being a Rhombicuboctahedron (would be) good for England.

Instruction to make the rhombicuboctahedron:
– Maths
– That’s it.

(If it helps, I made the squares with a side length of 62mm and the triangles 102mm.)

Huge thanks to my Patreon supporters who mean I can drop what I’m doing and spend two days writing/filming/editing such a ridiculous video just because I noticed a correlation involving triangles. https://patreon.com/standupmaths

I showed bits from these two old videos:

Big thanks to the roughly one million screaming children who were at some far side of the park I was filming in, but somehow still made their voices heard.

CORRECTIONS
– I should have mentioned that the England women’s football team reached the Euro finals in 1984 and 2009.
– Let me know if you spot any mistakes!
