How do you draw a cube?

Answer 1

To represent a 3-D cube as a 2-D drawing:

Draw two overlapping squares of identical size, where each of the four vertices (corners) is separated from its corresponding corner by a distance equal to the length of a side of the square. Draw lines between these corresponding corners and you have the appearance of a cube with all open sides.

By erasing various interior lines that would be blocked by a solid face, you can simulate three faces of the cube as seen from any of four directions: above left, above right, below left, or below right.

Looking inside a Cube

You can also create a simulation of a cube by drawing a slightly smaller square inside a square, and connecting the same corners. This creates the effect of looking down into an open cubical shape.
