It's right here, in your own calculation:

z = x * (Kg) * (Kg^-1) * (m^-3)

If the same unit of measurement is in the numerator and denominator, that unit cancels out, just as a numerical quantity would in an algebraic calculation. So kg*1/kg=1

It's confusing to write "corpses', a unit of measurement, as x, which is used to represent a numerical quantity. But I'll keep your notation.

So we have x * (Kg) * (Kg^-1) * (m^-3)=x/m^3

or corpses per cubic meter.
