    A cube of aluminum, whose volume is Va= .125 m^3, and whose density is Da= 2700 kg/m^3 is suspended from a cord which holds it stationary with the top surface horizontal and h= 2.2 m below the surface of fresh water.
    See attachment #1 showing known parameters.
    PART a. Find the mass of the aluminum.
    PART b. Find C, the force in the supporting cord.

    See attachment #2 showing forces.

    PART a. The density of a material is mass per volume, so:
    (1) Da= Ma/Va
    Substitution of knowns will give you:
    (2) Ma= 337.5 kg

    PART b.
    Whenever an object is at rest and ...
