Density is the mass per unit volume of a substance. In an equation form,

Density = mass / volume

For this problem:

Density = 42 g / 6.0 cm^3 = 7.0 g/cm^3

just divide, you do know now to do that.

Density is in g/cm³, you have mass in g and volume in cm³, it should be obvious from the units that you divide mass in g by volume in cm³ to get density is in g/cm³.

But in case you can't follow that...

density = 42 g / 6 cm³ = 7 g/cm³
