DENSITY

I have two objects with the same volume but different masses.  Which object will be more dense?

• The object with less weight.
• The object with more weight.
• The object with more mass.
• The object with less mass.

What is the formula for density?

• density = mass x volume
• density = mass / volume
• density = mass + volume
• density = mass - volume
• I don't know.
