Significant figures are the number of digits or the numbers that contribute to the actual value of a measurement.
Some of the rules to check the number of significant figures are:
- All non-zero digits are always significant
-Zeros in between numbers are significant
-Leading zeros after decimal are not significant
-Trailing zeros after decimal are significant
-If the final digit after decimal is greater than or equal to 5, it can be rounded up to the next higher number
The given value is:
