  1. $9$

  2. $7$

  3. $11$

  4. $5$

Show answer
Correct Option: B
Explanation:
Using Euler's formula

$V+F=E+2$ 

$E=15$

$V=10 $

$\therefore 10+F = 15+2$

$\therefore  F= 17-10 $

$\therefore F=7 $

  1. 0

  2. 1

  3. 2

  4. 3

Show answer
Correct Option: A
Explanation:

A point just marks a place which has no length, no breadth and no thickness.
