Answer :
To find the answer, you would use Dimensional Analysis, as follows:
[tex]31 meters * \frac{1 kilometer}{1000 meters} = 0.031 kilometers [/tex]
[tex]31 meters * \frac{1 kilometer}{1000 meters} = 0.031 kilometers [/tex]
The metric system is used for the measurement of the fundamental parameters. The building is 0.031 kilometers tall when it has a height of 31.0 meters.
What are units of height?
Height has been the measure of the distance that is vertical and depicts the tallness of the object. The height of the object can be measured in feet, inches, meters, centimeters, kilometers, etc.
The conversion factor for the height from meters to kilometers is given as,
1 meter = 0.001 kilometers
Given,
Height of building = 31.0 meters
Substituting values in the conversion data the height of the building in kilometers is calculated as
1 meter = 0.001 kilometers
31.0 meters =? km
Solving further,
(31.0 meters × 0.001 kilometers) ÷ 1 meter
= 0.0310 kilometers
Therefore, the building is 0.0310 kilometers tall.
