Lucy wanted to determine the density of a colorful stone that she had picked up on the beach. Which two properties must Lucy measure in order to calculate the density of the stone. A. Size and shape
B. Mass and volume
C. Mass and temperature
D. Composition and texture

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 :

, 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".
