i know how to find the mass(overflow can) but i need to know how to find the volume so i can divide the too to get mass(d=m/v)do you just read the marking on the graduated cylinder AFTER you have found the mass of the object? please help, thanks in advance!

Yes. Read and record the volume marking before you put the object in the graduated cylinder. After it's completely submerged, read and record the volume marking again.
Density = Mass / (Volume reading 2 - Volume reading 2)

You have to find the volume of this object by water submersion, first fill the cylinder with a known amount of water, drop the object in, and record how much the water level changes by, which means subtract the old recording from the new recording. Then divide the mass by the volume, which is the change in the volume of water.

Since you are determining the mass with an overflow can, this means the object floats, otherwise it would go completely in the can and sink. So you float it and the weight/mass of the displaced water is equal to the weight/mass of object.
Then you push the object below the surface of the water with a thin rod. The total water displaced is the volume.
The density is then (Vfloat / Vsunk)
