im confused as to how density is incorporated in this problems solution. any help as to how to solve this problem would be much appretiated.

consider a heavy cable of diameter d and density p from which hangs a load of mass M. what is the tension in the cable as a function of the distance from the lower end?

you need to figure out the total mass below a given point. this includes the mass of the rope too. you need the density of the rope to find the mass of the rope.
