Answer:

Counting Faces, Vertices and Edges

When we count the number of faces (the flat surfaces), vertices (corner points), and edges of a polyhedron we discover an interesting thing:

The number of faces

plus the number of vertices

minus the number of edges equals 2

This can be written neatly as a little equation:

F + V − E = 2

It is known as Euler's Formula (or the "Polyhedral Formula") and is very useful to make sure we have counted correctly!

cube

Example: Cube

A cube has:

6 Faces

8 Vertices (corner points)

12 Edges

F + V − E = 6 + 8 − 12 = 2

Step-by-step explanation:

A polyhedron is said to be a regular polyhedron if its faces are made up of regular polygons and the same number of faces meet at each vertex. This means that the faces of a regular polyhedron are congruent regular polygons and its vertices are formed by the same number of faces. A cube is a regular polyhedron but a cuboid is not a regular polyhedron as its faces are not congruent rectangles.
