The rules for identifying significant figures when writing or interpreting numbers are as follows:
All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5).
Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3.
Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2.
Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
By counting them.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.

4 of them.
1.056ml has four significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.

Three, so the answer would be 3.96. Always use the number with the smallest amount of significant figures to determine the amount of significant figures will be in the solution.
In order to determine the number of significant figures in a number, you need to look at the non-zero digits and any zeros between them.

Three - all nonzero numbers are significant.
1.056ml has four significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
4 significant figures.Zeros are significant if they are between two non-zero numbers, or if they are "trailing" zeros in a number with a decimal point.Eg.0.000047 = 2 significant figures4.7000 = 5 significant figures
Three significant figures are in this number.
