• Measure Density with cubes is
easy.
• What if they are rods or other non
cube shapes?
•Volume is a measure of the amount
of space an object takes up. When a
cylinder is submerged in the water it
pushes water out of the way. If you
measure the amount the water level
increases, you can find the volume of
the water pushed out of the way.
•Milliliters are equivalent to cm3.
•Mass is measured in grams.
•The units for density will be g/cm3.
