Understanding Density and Volume

What does density measure?

• The amount of mass a substance has per unit of its volume.

• The total mass of a substance.

• The total volume occupied by a substance.

• The weight of a substance in a given area.

Which of the following equations correctly represents density?

• Density = Volume / Mass

• Density = Mass × Volume

• Density = Mass / Volume

• Density = Force / Area

What are the standard SI units for density in physics?

• grams per cubic centimeter (g/cm³)

• kilograms per cubic meter (kg/m³)

• grams per liter (g/L)

• kilograms per cubic centimeter (kg/cm³)

An aluminum block has a mass of 420 kg. If the density of aluminum is 2710 kg/m³, what is the volume of the aluminum block?

• 0.155 m³

• 6.45 m³

• 1138200 m³

• 0.000388 m³

How is the volume of an irregularly shaped solid typically determined experimentally for density calculation?

• By measuring its length, width, and height.

• By submerging it in a Eureka can filled with water and measuring the displaced water.

• By using a balance to measure its mass.

• By observing its displacement in air.
