Sagot :
Centimeter is the right answer.
When a student performs an experiment and must measure the lengths of four different objects: a textbook, a pencil, a cup, and a piece of bread, centimeter would be the most appropriate unit of measurement for her to use.
The other units are either too small or too big to use for the measurement of the given objects.
Kilometer
On considering kilometer we usually use the kilometer unit of measurement for the measurement of distance.
Meter
Considering meter, we can tell that 1 meter = 100 centimeters which is also more when measuring the above given objects.
Micrometer
Micrometer is very small to measure the above mentioned objects.
The micrometer is a commonly used unit of measurement for infrared radiation wavelengths, bacterial and biological cell sizes, and for classifying wool according to the diameter of the fibers.
So hence on comparing all the units we can conclude that centimeter is the appropriate unit of measurement to measure a textbook, a pencil, a cup, and a piece of paper.
