ELI5: Explain Like I'm 5

10-demicube

So, have you heard of cubes before? They're like boxes, you can draw them on a piece of paper with four lines and make them three-dimensional by adding extra lines. Then, you can imagine that you have tiny toys that are cubes that you can stack up and play with.

Now, imagine that you could stack up ten of these cubes on top of each other. Each cube would have six faces (top, bottom, left, right, front, and back). So, if you multiply six by ten, you get 60 faces! That's a lot of faces, right?

But wait, there's more! Let's not forget about the edges of these cubes. Each cube has 12 edges, which are where two faces meet. If you add up all of the edges from these ten cubes, you get 120 edges. That's even more than the 60 faces!

Now, if you add up all of the corners (where three edges meet) from these ten cubes, you get 80 corners. That's even more than the edges!

So, in summary, a 10-demicube is like stacking ten cubes on top of each other. It has a lot of faces, edges, and corners. It's a really cool shape that you can imagine in your mind or draw on paper.
