Is a 4 spacial dimension cool?
It turns out a tesseract is an hypercube with a surface made of eight 3-dimensional cubes, whereas a cube has a surface made of six 2-dimensional squares and a square has a surface made of four 1-dimensional lines.
But, when it comes to actually calculate the area or volume of these figures, the dimensional gaps usually become visibly more consistent.
A straight line has no area, a square does. The volume of a cube made of many of those squares is much bigger.
Imagine in a 4 Euclidian spacial dimension, the analogy of a 3 dimensional cube is a hypercube. Its hypervolume is obtained by height x width x depth
x spissitude. That's even much bigger.
