Density represents the mass per unit of volume of a substance.

Since you do not have a volume expressed in your equation, I'll assume you mistyped it. The mass of the substance is expressed in grams, which can be used for density, but #"cm"# cannot be used since it represents a unit of length.

A proper unit for volume would be #"cm"^3#, which would make your equation

#rho = ("24 g")/("8 cm"^3) = "3 g/cm"^3#

This means that a cube with the dimensions #"1 cm x 1 cm x 1 cm"# filled with your substance weighs #"3 grams"#.
