What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume

What is the volume of this prism?

• 18 cubic cm
• 6 cubic cm
• 9 cubic cm

To find the volume you:

• Divide length x width  x  height 
•  length + width  +  height 
•  length x width  x  height 
• none of the above

Why does ice float in water?
