Answer:
The mass and the volume of the object.
Step-by-step explanation:
Density of an object is simply defined as the mass of the object per unit volume of object. Mathematically, it can be expressed:
Density (D) = mass (m) /volume (V)
D = m / V
From the definition and formula of density, we can see that the density of an object can be obtained if we know the mass and the volume of the object.
