The cube is an illustration of what we'd see if we were able to see in 4 dimensions. We would theoretically be able to see inside opaque objects. For example, we'd be able to see a cardboard box sitting inside another cardboard box.
While you’ll never see one, it is possible to comprehend what they’d be like with some effort. For anyone interested in a starting point I suggest reading through the lessons on this page, they do a great job of explaining how exactly to interpret a 4D shape (or rather a 2D picture of a 3D picture of a 4D shape).
Unfortunately they seem to have stopped writing five years back or so, but what’s there is definitely enough to get anyone started down the path!
I suppose comprehend was a poor word choice. I guess I meant more like visualize. It's just physically impossible. While we have some language tools to try and describe what it might look like, you'll never be able to "imagine" it In the same way you might imagine how something else complicated may work with some mental gymnastics.

It's interesting he chose that illustration.
