• 9g/cm3

• 5184g/cm3

• .11g/cm3

• 322mL

What two types of measurements make up DENSITY? 

• Mass and Volume
• Temperature and Mass
• Grams and Centimeters
• Volume and Weight

Frank has an eraser. It has a mass of 4 g and a volume of 2cm³. What is the density?

• 2 g/cm³

• 4 g/cm³

• 8 g/cm³

• 2 g/in³

Mass = 8 g, Volume = 4mL..... what is the density?

• 12 g/mL

• 32 g/mL

• 4 g/mL

• 2 g/mL

Answer explanation

Density equals mass divided volume.

The mass of the object is 8 grams.

The volume of the object is 4 mL.

8 divided by 4 is 2.

So the density is 2 grams/mL.

What is the density of an object that has a mass of 264g and a volume of 12mL?

• 22 g/mL

• 252 g/mL

• 3,168 g/mL

• 278 g/mL
