Question

Garth estimated the height of the door to his classroom in meters .What is a reasonable estimate?

Answer 1

The most reasonable answer would be 2 meters since two meters equals about 6 feet.

Answer 2

Solution:

The three units of measurement that we use in day to day life is ,Centimeter, Meter and Kilometer.

Centimeter being the smallest, and Kilometer largest when comparison is made between three.

1 meter= 100 cm

1 kilometer= 1000 meter= 100000 centimeter

If we measure the height of Door of classroom in centimeters suppose it is approximately 223 cm, it is better to convert it into a better unit of measurement which is higher than centimeter ,as 100 cm is equal to a meter. So, instead of writing 223 cm it is better to write 2.23 m, neither 0.223 Km.So, if the number lies between 100 cm ≤number <100,000 cm,  convert it into meters by dividing the number by 100, which is best units of measurement.
