Measurement is the quantification of an object's or event's attributes so that they can be compared to other objects or occurrences. In other terms, measurement is the process of establishing how large or little a physical quantity is in comparison to a similar basic reference quantity. Measurement's breadth and application are determined by the environment and discipline. Measurement do not apply to nominal qualities of objects or events in natural physics and technology, which is in keeping with the principles of the International lexicon of metrology established by the International Organization of Weights and Measures.

Answer:

The answer is 8

There is just one digit in each measured number that is unknown ( the last digit written). It reflects the precision of the scale used to make the measurement.

41.68cm

The numeral on the right is the least significant, while the digit on the left is the most significant.

So, 8→ most insignificant

4→ most significant

Any measurement's last digit is calculated, and it is this calculated digit that shows uncertainty. The lower the amount of uncertainty, the more decimal places there are.
