@robinhouston@mathstodon.xyz It’s not obvious! Perhaps because 12 is a big number - too big to just see and know how many without counting.

@henryseg@mathstodon.xyz Absolutely! It's not obvious at all. That's why models like this are such a great tool.

@henryseg@mathstodon.xyz My reaction was to say "No way! The top and bottom of the cube are squares, 8 edges, the top and bottom of the octahedron are triangles, 6 edges, and the edges connecting the the top and bottom are.... oh wait, there are two of them from each vertex, hmm let me count". @robinhouston@mathstodon.xyz
