# Problem: The density of a human body can be calculated from its weight in air, Wair, and its weight while submersed in water, Ww. The density of a human body is proportional to:A. Wair/(Wair – Ww). B. (Wair – Ww)/Wair.C. (Wair – Ww)/Ww. D. Ww/(Wair – Ww).

The relative density, ρ of a body is given by:

$\overline{){\mathbf{\rho }}{\mathbf{=}}\frac{{\mathbf{\rho }}_{\mathbf{a}\mathbf{i}\mathbf{r}}}{{\mathbf{\rho }}_{\mathbf{a}\mathbf{i}\mathbf{r}}\mathbf{-}{\mathbf{\rho }}_{\mathbf{w}\mathbf{a}\mathbf{t}\mathbf{e}\mathbf{r}}}}$

Density in terms of volume, V:

$\overline{){\mathbf{\rho }}{\mathbf{=}}\frac{\mathbf{m}}{\mathbf{V}}}$
