A rock is placed in a graduated cylinder to determine its volume. The following data are obtained. What is the volume of the rock?

Initial volume of water: 13.7 mL
Final volume of water: 28.9 mL

1 answer

if the rock is completely submerged, then its volume is 28.9-13.7 mL

That's how much more stuff is in the cylinder after the rock is covered up.
