Answers:
a) [tex]kg/m^{3} [/tex]
b) derived
Explanation:
Density [tex]D[/tex] is a characteristic property of substances and materials and is defined as the relationship between the mass [tex]m[/tex] and volume [tex]V[/tex] of a specific substance or material, as shown below:
[tex]D=\frac{m}{V}[/tex]
This means density is inversely proportional to volume.
In addition, density is a derived unit, because is based on two basic units of the International Sistem of Units: Mass (kilograms) and Volume (cubic meters)
