Which choice best describes what would happen if a cube with a density of 0.2 g/mL were placed in a container of water? A. It would float with about 80% of the cube below the surface of the water and 20% above the surface.

B. It would float with about 20% of the cube below the surface of the water and 80% above the surface.

C. It would sink to the bottom.

D. It would fly away.

A. It would float with about 80% of the cube below the surface of the water and 20% above the surface.

Explanation:

The choice that best describes what happens to cube of the given density value is that it would float with about 80% of the cube would be below the surface of the water and 20% above the surface.

Density is the mass per unit volume of a substance. The more mass a body has relative to volume, the great it's density. In short, density is directly proportional to mass and inversely related to volume.

The density of water is 1g/mL

If the density of the cube were to be the same with that of water, the substance will just mix up with water .

Here the density is less than that of water.

The density is 0.2g/mL

Therefore, 20% will stay afloat and 80% will be below the surface of the water.
