A square and a cube are two different shapes.
A square is a 2-D shape with four sides equal in length (with an edge on the bottom, if the bottom of the shape was a vertex it would be a diamond). A cube is a 3-D shape composed of six squares. xD
It is interesting that you automatically assume that I'm not thinking deep enough, especially as the way I see it you are the one taking a view that is too simplistic.
I wasn't changing the context because mathematics is a human language xD
As for that last part, who doesn't love a good debate? :D
