Calculating Density and Related Problems

What is the definition of density?

• How much space an object takes up

• The amount of mass in a given volume

• The weight of an object compared to its size

• How heavy something feels

Two objects have the same mass, but one takes up more space. Which statement is true?

• The object that takes up less space has greater density

• Both objects have the same density

• The object that takes up more space has greater density

• Density cannot be compared without knowing weight

Which box has a higher density?

• Box A

• Box B

• They are both the same density

What is the formula for density?

• density = mass x volume

• density = mass + volume

• density = mass/volume

• density = mass - volume
