Identify all the digits in the number 0.0560 and determine which are significant. Significant figures include all nonzero digits, any zeros between them, and any trailing zeros in the decimal portion.
Ignore the leading zeros before the first nonzero digit, as these are only placeholders and not significant.
Count the digits starting from the first nonzero digit (which is 5) to the end of the number, including any trailing zeros after the decimal point.
