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.
