The properties of a cube are listed below:

Mass = 80 g

Length of side = 2 cm

What is the density of the cube?

10 g/cm3

20 g/cm3

160 g/cm3

640 g/cm3

In order to calculate for the density just divide the mass with the volume of the object. Since the problem states that it is a cube, the volume would just be the cube of the side length which is 8 cm^3. Then the mass which is 80 g would be divided with 8 cm^3. Thus the volume is 10 g/cm^3.
