Let A be a pyramid on a square base and B be a cube. Let a, b, c denote the number of edges, number effaces and number of corners respectively. Then the result \[a=b+c\]is true for:

A) Only A

B) Only B

C) Both A and B/A

D) Neither A nor B

Correct Answer: D

Solution :

For cube figure:- Edges, a= 12, Faces, b= 6, Comer, c= 8 For pyramid figure Edges, a=8, Faces, b= 5, Comer, c= 5 So, a = b + c is neither true for cube nor for the pyramid.
