Figure shows a measuring scale which is usually supplied with a geometry box. Which of the following distance cannot be measured with this scale by using it only once?
- 0.1 m
- 0.15 m
- 0.2 m
- 0.05 m
Answer
1 m = 100 cm
So, 0.1 m = 10 cm
0.15 m = 15 cm
0.2 m = 20 cm
0.05 m = 5 cm
The distances 10 cm, 15 cm and 5 cm can be easily measured by using a 15 cm long scale, while the distance 20 cm cannot be measured by using this scale only once.
The correct option is C.
