  1. mass = volume x density
    Rearrange to get
    volume = mass/density

  2. Do you not know how to rearrange these formulas.
    mass = volume x density. Let's use letters.
    m = v x d
    To solve for v, we want to get v on one side an everything eles on the other. How can we do that?
    m = v x d.
    We divide both sides by d.
    m/d = v*d/d
    m/d = v

    OR, if we wanted to solve for density.
    m = v x d
    Divide by v (so the v cancels)
    m/v = v*d/v
    The v cancels and we have left
    m/v = d
    or mass/volume = density.
