Given information

Given number :  

Step-by-step explanation

Rules to find significant figures for zero:

• Leading zeros (present at the beginning of a number) are not significant.
• Trailing zeros (present at the end of a number) are not significant.
• Trailing zeros present after the decimal are significant.
