Iron Teacup

Homework Help! Questions about mass, volume, and density! Please Help!?
Mass ?- What has the greatest mass:a balloon, an iron wrecking ball, a basketball, or a baseball?
Volume ?- What has a greater volume: a teacup, a barrel, or a milk carton? (I know this one is easy, I just want to make sure of my answer.)
Density ?-Each cube has measures 10cm^3. Which cube has the greatest density: a balsa wood cube, a plastic cube, or an ice cube?
Mass= Density x Volume
Volume= Mass/Density
Density= Mass/Volume
Please and Thank you!
Mass = an iron wrecking ball
Think of mass as how heavy something is. Mass is NOT the same thing as weight though.
Volume, assuming everything normally sized, the barrel hold the greatest volume.
Think of volume as a cubic area. 1 cm is a unit of measure, 1 cm squared is a unit of area, 1 cm cubed (1 cm x 1 cm x 1cm ) is a unit of volume. Also note, 1 cm cubed is equivalent to one (ml)
Density : thats a bit tougher to judge without the mass of each. I would guess the plastic cube has the highest density.
