If the smallest markings on a graduated cylinder are one tenth (1/10) of a milliliter, which of the following measurements could be recorded using that graduated cylinder?

10 mL

10.1 mL

10.05 mL

10.050 mL

If the markings on a measurement apparatus are a certain distance apart, we can usually estimate one decimal place beyond that. So for markings 0.1 ml apart, we can estimate to the nearest 0.01 ml, which would be 10.05 in this case.
