Density is equal to

volume divided by mass

mass divided by volume

they are all equal to each other

For this case we have that by definition, the density of a body is given by:

ρ

Where:

M: It is the mass of the body

V: It is the volume of the body

So the correct option is:

"mass divided by volume"

mass divided by volume

ρ=

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
