That’s only one way (and the easiest) to represent a hypercube.
Another way is to envision two 3d cubes, “open” the corner of one and place it “inside” the other, and connect all the corresponding corners. The resulting 8 cubes, as is in the prior illustration, have 2 that look “normal” and 6 that are skewed due to the down-dimensioning representation in 3d.

Read “And he built a crooked house” by Heinlein for more detail.

Also good to keep in mind is that this object, if moved along the 4th axis through the 3D space you are observing would appear as a point and grow to a full sized cube then shrink again to a point before vanishing from your view. To your perception, it would always be a cubic object or a point.
