The density of different tissues, namely fat, flesh and bone are markedly different, to the point that some weight loss clinics used density as a measure of fatness.
Secondly is that proportions do vary to some degree among the population, having it as a factor would allow for normalization of the data across the population and accounting for the percentage of bone in a body.
With height as a good approximate for 'ideal' volume, and k to normalize data, and the actual density of a person we can have a rough index of flesh to fat proportions, using weight and height and assuming everyone has the same k, we get an even more rough idea of the composition of someone's body.
Now of course a urine test for fatty acids is a far better indicator that weight clinics now use.
