What is a cube as a 2D shape?

A cube is a three-dimensional geometric shape, not a two-dimensional one. However, when considering a cube in a 2D context, it can be represented as a series of squares that depict its faces in a net format or as a projection, such as an isometric drawing. In essence, a 2D representation of a cube captures its structure using lines and shapes, but it does not convey the full depth and volume of the actual cube.
