    because you measure the volume of water before the object is put into the water

    and after the object is in the water then subtract the 2 volumes

    Yes an easy way to remember density is \[\frac{ M }{ V } \] which kind of looks like a heart if you write it out

    Note: All the above discussions refer to a sinking object. Procedure is different if object floats on the fluid!
