Calculating Density of Regular and Irregular Objects

If an object has a density of 3.6 g/mL and you put it into water, will it sink or float?  

• sink

• float

Using the picture, tell me which object is the least dense and why?

• The fish because he is in the middle

• The cork because it is floating at the top of the water

• The rock because it is at the bottom

• The cork and the rock because they have the same about of atoms.
