Question

Find the value of 'F + V - E' (F-Faces; V-Vertices, E-Edges) for the given cube.

• A. 2
• B. 3
• C. 0
• D. 1

Answer 1

The correct option is A 2

The given image is of a cube.
Let's count the number of faces, edges and vertices of a cube.


So, properties of a cube are:
Faces (F): 6
Edges (E): 12
Vertices (V): 8

We have to calculate the value of $F+V-E$.

$F+V-E=6+8-12$
$=14-12$
$=2$

Therefore, the value of $F+V-E$ is $2$.
