Conclusion: The number of significant figures is directly linked to a measurement. If a person needed only a rough estimate of volume, the beaker volume is satisfactory (2 significant figures), otherwise one should use the graduated cylinder (3 significant figures). So, does the concept of significant figures deal with precision or accuracy?

12 has two significant figures and 3.00 has three, so the answer should only have two. For example, 3.20 x 5.04 = 16.128 ( 16.1. The starting values only have three significant figures each, so round the answer to three significant figures, 16.1.

Rules for Determining the Number of Significant Figures in a Measurement . All non-zero digits are counted as significant figures. Examples: 673, 6.73 and 0.673 all contain 3 significant figures. Zeros between non-zero digits are counted as significant figures. Examples: 506 and 701 both contain 3 significant figures.
