Question
The Qutab Minar is 72 meters high.
- About how many meters high is your classroom?
- Guess how many rooms, one on top of the other, will be equal to the Qutab Minar.
- Explain how you made a guess.
Solution
- My classroom is about 3 metres high.
- The height of Qutub Minar = 72 m
Number of rooms one of the tops of the other
= `"Height of Qutub Minar"/"Height of one room"`
= `(72" m")/(3" m")`
= 24 m. - I made a guess on the basis of the height of my classroom.
