You should remember that the density in SI units is Kg per cubic meter, hence, you should convert the grams in Kilograms such that:

`6.4*105 g = 6.4*105*10^-3 Kg`

`6.4*105 g = 0.0064*105 Kg`

`6.4*105 g = 0.672 Kg`

**Hence, converting the given density to an accepted SI value yields `rho = 6.4*105 g/(m^3) =0.672 Kg/(m^3).` **
