    First calculate the volume of the rectangular prism by multiplying its length, width and height. The volume of the prism is 8 cm^3. Since density is known to be mass over volume, just multiply the given density with the volume. The mass of the prism then is 960 grams.

    and Since density is the ratio of the substance's mass to its volume,

    Density = Mass/Volume

    Mass = Density*Volume

    The volume of a rectangular prism is:

    V = LWH = 4*2*1 = 8 cm³

    Mass = (120 g/cm³) (8 cm³)

    Mass = 960 grams
