Question

Which of the following is not part of polyhedron.

a. Face
b. Vertex
c. Oblique
d. Edge

Answer 1

C

Explanation:

Oblique. The other three are used to describe a polyhedron. They are related by the following formula

V + F - E = 2.

Where

• V = number of vertexes
• F = the number of faces
• E = edges

For example consider a common cube, like a sugar cube.

It has 6 faces (f)

It has 8 vertexes (V)

It has 12 edges. E

6 + 8 - 12 = 14 - 12 = 2
