The Number of the significant figures in the given measurement is 3.

The number of significant figures is determined by simply calculating the number of digit in any mathematics number.

But there are certain rules which must be followed for determining the significant numbers :-

  • Zeroes before the non-zero number must not be counted in significant figures.
  • Zeroes after the point should not be counted if there will no non-zero number after decimals.
  • If there is an non-zero number, then they should be counted.
  • If the zero is before the decimals and there are certain non-zero numbers after the decimals then all the zeroes should be counted in significant figures.
  • Zeroes in between of the non-zero numbers is always counted.

Thus, By following the given rules, we may say, that this number has 3 significant digits.

Hence, the Number of significant digits in measurement will be equal to that only, i.e. 3.


Hope it helps.
