It is not so simple to explain in few words; see the link below.
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.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Three - all nonzero numbers are significant.
The number 805 has three significant figures.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
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.
3 of them.
4 of them.
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.

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.
