Phillip is correct, but I will add the definition of a derived unit is one that is obtained by using a formula and other measurements. that were actually taken.

Density is not an absolute measurement but must be qualified by stating the specific conditions under which the measurements were taken.
The density of a gas (for instance) will depend on the pressure and the temperature of that gas when the density measurement was taken. Any change in temperature or pressure will change the density.

Because the unit of density is derived from 2 fundamental units, which are, kg (for mass) and m (metre, for length). Or g (grams for mass) and cm (for centimetre). And of course, the length is cubed.
I don't know what the above 2 answerers are talking about.
