A pop and cute triangular pyramid painted in four different colors

I think it's probably a math textbook or something.

It is unclear what is to be learned

I don't know if it's actually a textbook.

Made of plastic and has a light texture

Put them in a transparent container or just line them up.

It looks like you can enjoy various ways of placing it.

As an aside, when I saw this, I thought of the four color theorem.

When coloring a flat map so that adjacent colors do not overlap

All you need are four colors

It might be fun to prove it with this triangular pyramid.
