What tools would you need to use if you are going to make the measurements necessary to calculate the density of a rock

I believe you would use a graduated cylinder mark the volume inital volume of the cylinder and then the final

then minus the final volume - the inital to give the volume

then you would put the rock on a scale and get the mass

then you use the "equation of love"

mass/ volume = density

m/v = density

output?
