Question

Using Euler's formula, find the value of
(F + V - E ) for the given figure.

• A. 2

Answer 1

The correct option is A 2


A face is a single flat surface of the object.

An edge is a line segment between the faces.

A vertex is the corner point where two or more edges meet.

So, the given figure has:

• 8 faces $\left(F\right)$
• 6 vertices $\left(V\right)$
• 12 edges $\left(E\right)$

$\therefore F+V-E=8+6-12=2$
