• 1,152 g/cm³
• 0.5 g/cm³
• 72 g/cm³

If you have a gold brick that is 2 cm by 3 cm by 4 cm and has a density of 19.3 g/cm³, what is its mass?

• 463.2 g/cm³
• 463.2 g
• 0.804 kg
• 0.804 g

What is the volume of Object X?

• 10.0 cm³
• 15.0 cm³
• 20.0 cm³
• 25.0 cm³

• 200 cm³
• 0.005 cm³
• 200.0 ml
• 72 ml

Find the density of a 2 cm x 2 cm x 2 cm cube with a mass of 64 g.  (Hint: find the volume first!)

• 6 cm³
• 12 g/cm³
• 128 g/cm³
• 8  g/cm³

Jen is explaining the difference between weight and mass to her sister. In comparing the two, which of the following could Jen use to CORRECTLY describe the weight of an object?

• Weight is the same everywhere in space.

• Weight is how much matter is in an object.

• Weight is the amount of gravitational pull on an object.

• Weight is not impacted by the force of gravity.

Which units of measurement are used for volume?
