    Answer:  60 grams

    ========================================================

    Explanation:

    m = mass

    v = volume

    d = density

    The formula we use is

    d = m/v

    Multiplying both sides by v allows us to solve for m

    d = m/v

    d*v = m

    m = d*v

    Now plug in the given density (d = 4) and the given volume (v = 15) and simplify:

    m = d*v

    m = 4*15

    m = 60 grams

    Note how,

    d = m/v

    d = 60/15

    d = 4

    which helps confirm our answer
