Partial cube

Hey there kiddo! Have you ever played with building blocks? A partial cube is like a big, fancy block made out of smaller blocks.

But these smaller blocks aren't just any old blocks. They are cubes! You know what a cube is, right? It's basically a square that pops out into the third dimension. So if you stack a bunch of cubes on top of each other, you get a rectangular block.

Now, imagine taking that rectangular block and slicing off some of the corners. What's left is a partial cube!

But wait, there's more! The really cool thing about a partial cube is that it's still made up of cubes. In fact, every corner of the block is a cube corner!

So, a partial cube is just a special kind of block made up of smaller cube blocks that have had some of their corners cut off. Pretty cool, right?
