Answer:

Planar Graph

When we draw dots and lines alone, it becomes a graph.

We obtain a planar graph when no lines or edges cross each other.

We can represent a cube as a planar graph by projecting the vertices and edges onto a plane.

One such projection looks like this:

According to the Euler's formula graph theory,

Number of dots − number of lines + number of regions the plane is cut into = 2.
