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

A) only A
B) only 3
C) both A and B
D) neither A nor 8

Correct Answer:




D) neither A nor 8

Description for Correct answer:

For cube figure,

Edges, a = 12 :

Faces, b = 6

Corners, c = 8

For pyramid figure,

Edges, a =8

Faces, b = 5

Corners, c = 5

So, a = b + c is neither true for cube nor for the pyramid.
