Density is defined as the mass of a substance contained per unit volume. In simpler words, density is a characteristic property of matter that defines how heavy or light it is. Heavier substances have greater densities than lighter substances.

The formula for density is:

Note that we need our density value in the units of g/cm³. So, we will be following these steps:

• We will convert our mass (40 lb) to gram units.
• We will convert the container dimensions (14 x 20 x 30 in) to cm units.
• We will find the volume of the container from its dimensions.
• We will use the mass and volume to calculate density.

So, let’s begin.
