How do you measure mass?

How do you determine the volume of...
  • A cuboide?
  • A cylinder?
  • An irregular object?

Slide 16 - Diapositive

Measuring mass: use a scale

Measuring volume:
  • cube or cuboid —> length x width x height
  • Volume Cylinder —>    
  • Irregular shaped object —> use a measuring cylinder
