Calculating Density

Unit 4 Calculating Density

by Ms. Medina and Ms. Reister

Multiple Choice

What is the formula for density?

• Density = mass X volume

• Density = mass / volume

• Density = mass + volume

• Density = mass - volume

Multiple Choice

Which formula can be used to find the volume of a rectangular prism?

• length x width

• length x width x height

• height x length

• length + width + height

Multiple Choice

What is the volume of this rectangular prism?

• $$48\ cm^3$$  

• $$12\ cm^3$$  

• $$20\ cm^3$$  

• $$32\ cm^3$$  

Multiple Choice

Volume is the amount of space an object takes up?

• True

• False

Multiple Choice

• 25 mL

• 20 mL

• 24 mL

• 30 mL

Multiple Choice

Let's practice! Before the volume is 50 ml. After the object is added it goes up to 60 ml. What is the volume of the blocks? (HINT: subtract the two volumes)

• 8 ml

• 60 ml

• 5 ml

• 10 ml

Multiple Choice
