Question

The properties of a rectangular prism are listed below: Density = 120 g/cm3

Length = 4 cm
Width = 2 cm
Height = 1 cm
What is the mass of the rectangular prism?

Answer 1

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

Answer 2

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.
