To what volume reading does the ethanol rise?

Question

An irregularly shaped piece of lead weighs 10.0 g. It is carefully lowered into a graduated cylinder containing 30.0 mL of ethanol, and it sinks to the bottom of the cylinder. To what volume reading does the ethanol rise?

Answer 1

Look up the density of lead, and then work out what volume the 10.0g piece of lead occupied, using vol = mass/density.

Then simply add that to the 30.0 ml of ethanol.
