Answer 1

Answer:

It is very important to estimate the size or magnitude of a physical quantity before it is measured. It gives you an idea about the scale to use to make an accurate measurement. Suppose you want to measure the length and breadth of your room. First estimate the order- will it be in centimeter or meter or kilometer etc.
