Answer:
The cube A is magnesium, the cube B is aluminum and the cube C is silver.
Explanation:
Density is defined by the expression where m is the mass and V is the volume, therefore:
- Density of the cube A:
- Density of the cube B:
- Density of the cube C:
Solving for mass:
And all the three cubes have the same mass, so:
Therefore:
(Eq.1)
(Eq.2)
Solving for in Eq.1:
Replacing values for the volume:
As we know the density of the aluminum is , so replacing this value for
:
that is the density of the magnesium.
Solving for in Eq.2:
That is the density of the silver.
Therefore the cube A is magnesium, the cube B is aluminum and the cube C is silver.
