Metals are usually more dense than wood. pick the statement below which accurately compares metals to wood. metals have less mass per unit volume than wood.
metals have more mass per unit volume than wood.
metal and wood have the same mass per unit volume.

Metals have more mass per unit of volume than wood.

Explanation:

Density is defined as the amount of matter contained in a unit of volume. A material that is denser than another will therefore have more mass per unit of volume.

The density of a body can affect buoyancy, bodies with low enough densities can float in fluids. For example wood can float in water while metals can't.

any one of the statements could be an accurate comparison. but the statement that would define the correct choice and seal the deal is not even on the list:

"the visibilities of vector-x and vector-y in the drawing provided with the question are identical and nonexistent."
