6. Finding Volume Liquids (water)
Place the liquid in a graduated cylinder and read the level
Regular Object (block)
L * W * H
Irregular Object (rock)
Do Water Displacement
Subtract water level without object from water level with object

7. Density
Density of water is 1 g/mL
Less means float
More means sink

8. Density Mass per unit Volume Unit: g/mL or g/cm3 Formula
Density = mass (needs to be in grams)
volume

9. Practice Density Question
Steps:
Write density equation
Identify variables that are given
Identify variable missing
Solve for missing variable
An aluminum block has a density of 2.7 g/cm3 and has a mass of 33g.
