The number 3567 has to be rounded off or added with zeros, so that it has three significant figures in it. Concept Introduction: In measurements, the term rounding off means, deleting the unwanted non-significant figures from the calculated values. If the digit to be deleted is less than 5, then the remaining digits are simply dropped. If in case the digit to be dropped is5 or more than 5, the last digit is increased by one and retained.
