Density

A rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

• 7 mL

• 7 g/cm³

• 28 g/cm³

• 1/7 g/cm³

What is the formula for density?

• density = mass x volume

• density = mass / volume

• density = mass + volume

• density = mass - volume

An eraser has a mass of 4g and a volume of 2cm³. What is its density?

• 8 g/cm³

• 2 g/cm³

• 1/2 g/cm³

• 24 g/cm³

Which box has a greater density?  

• Box A

• Box B

Aiden and Noah are comparing two objects. "The balls have the same ​ (a)   , but the foam ball has more ​ (b)   .

So, the ​ (c)   has more density.

• mass

• volume

• marble

• foam ball

Answer explanation

Aiden and Noah state that the balls have the same mass but the foam ball has more volume. Since density is mass divided by volume, the marble must have more density than the foam ball.

"The balls have the same ​ (a)   , but the foam ball has more ​ (b)   .

So, the ​ (c)   has more density.

• mass

• volume

• marble

• foam ball
