Can you visualize this simple rotation in 3 dimensions?

Imagine a line drawn through the middle of the top left edge of a cube and the middle of the bottom right edge. Now rotate the cube180 degrees around the line. Do you see that the cube ends up occupying the same space? I had read this and had the hardest time visualizing it. I used a Rubik’s cube to finally figure it out. Where do the top and bottom faces of the cube end up?
