The correct answer to the question is:

Option A. If you compare equal volumes of lead and styrofoam, the lead would be heavier (have more mass)

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance.

Density = mass /volume

We shall compare the densities of lead and styrofoam.

Density of lead = 11.29 g/cm³

Density of styrofoam = 0.05 g/cm³

For lead:

From the density of lead (i.e 11.29 g/cm³), we can see that for every 1 cm³, the mass of lead is 11.29 g

For styrofoam,

From the density of styrofoam (i.e 0.05 g/cm³), we can see that for every 1 cm³, the mass of styrofoam is 0.05 g

Thus, at equal volume, lead has a higher mass than styrofoam.

Therefore, the correct answer to the question is:

Option A. If you compare equal volumes of lead and styrofoam, the lead would be heavier (have more mass)
