Answer 1

Answer:

This can be written: F + V − E = 2

Try it on the cube:

A cube has 6 Faces, 8 Vertices, and 12 Edges,

so:

6 + 8 − 12 = 2

Answer 2

What is Euler’s Formula?

• Before we go through the Euler’s formula, let’s know about the polyhedron shape in a bit more detail. A polyhedron is a solid object whose surface is made up of the flat faces which are bordered by the straight lines only. In it, each face is, in fact, a polygon. A polygon is a closed shape in the flat 2-dimensional plane which is made up of points joined by the straight lines.
