Solved Example on Net

Ques: Which of the nets can be folded to form a cube?

Choices:

A. Net $c$
B. Net $b$ and Net $c$
C. Net $b$, Net $c$, and Net $d$
D. Net $b$
Correct Answer: D

Solution:

Step 1: A cube does not have a rectangular base or face. So, net $a$ does not form a cube.
Step 2: A cube has only 6 squares in it. Nets $c$ and $d$ have 7 squares. So, they do not form a cube.
Step 3: If you fold net $b$ with square 1 as the base, you get a cube. So, net $b$ folds to give a cube.
