Answer:
[tex]\Huge \boxed{\mathrm{5 \ kg/ml}}[/tex]
Explanation:
[tex]\sf \displaystyle density = \frac{mass}{volume}[/tex]
[tex]\displaystyle \rho = \frac{m}{V}[/tex]
The mass of the object is 20 kg.
The volume of the object is 4 ml.
[tex]\displaystyle \rho = \frac{20}{4}[/tex]
[tex]\displaystyle \rho = 5[/tex]
The density of the object is 5 kg/ml.
