I could guess but I can't seem to find the answer any where. Interestingly enough I think one of the standard IQ questions is to count how many sides a shape has, so I definitely don't want to guess

Trying to display a hyper cube on a 3d surface is like trying to display a cube on a 1 dimensional line. The information you get, although be it true, reveals no insight into what the shape really is.

You don't count the sides of the inner cube, but only the sides of the outer cubes. The simplefied model has 20 sides. Last edited by myequasion; October 20th, 2016 at 04:27 AM.
