If a measurement is recorded as 0.00456 m, how many significant figures are in this measurement?
Step 1: Look at the number 0.00456.
Step 2: Identify the leading zeros. These are the zeros before the first non-zero digit (4).
Step 3: Count the significant figures. The significant figures are the non-zero digits and any zeros between them or after them.
Step 4: In 0.00456, the significant figures are 4, 5, and 6.
Step 5: Count the significant figures: 4, 5, and 6 gives us a total of 3 significant figures.
Significant Figures – Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion.
Leading Zeros – Leading zeros are the zeros that precede all non-zero digits in a number and are not counted as significant figures.
