Answer:
B. Mass and volume
Explanation:
The density of an object is given by its mass per unit is volume. Its mathematical form is given by :
[tex]\rho=\dfrac{m}{V}[/tex], [tex]\rho[/tex] is a symbol of density of an object
If mass is in g and volume is in cm³, the density is given in g/cm³ and if the mass is in kg and volume is in m³, the density is given in kg/m³.
Hence, two properties must Lucy measure in order to calculate the density of the stone are "mass and volume".
