THEORY: Volume is the amount of space an object takes up. It is measured in liters (L), milliliters (mL) or cubic centimeters (cm3 or cc). A cc is exactly the same volume as an mL and a liter is WebConclusion: 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) or better yet, the buret (4 significant figures). the more things stay the same
