    Yes, these formulas are correct. The formulas are easily derived through the equation m = pV

    "m" is the mass of the object.
    V is what you have to calculate as the volume.
    p is the density.

    The website is simplifying this formula into situation specific equations which can be derived from common variables you might know.
