If the number of vertices, edges and faces of a rectangular parallelopiped are denoted by v, e and f respectively, the value of (v - e + f) is

A. 4

B. 1

C. 0

D. 2

Answer: Option D

Solution(By Examveda Team)

We know that
A parallelopiped has vertices (v) = 8
edge (e) = 12
face (f) = 6
Put into equation (v - e + f)
⇒ 8 - 12 + 6
⇒ 2
