Density, Mass and Volume

• Density, Mass and Volume

  • Density (ρ) is mass per unit of volume
  • Measure how compact a substance is
  • Mass compared to the amount of space is takes up

  ρ = m/v ρ = Density (kg/m³)

  m = Mass (kg)

  v = Volume (m³)

  • Water can support 1000 kg/m³ (1 kg at a time, supports the same vol in different density)
• Volume of a Cube

  .

  A) Cube

  B) Length * Width * Height

  
• Volume of a Sphere

  .

  A) sphere

  B) 4/3 * π * r³

  
• Volume of a Cylinder

  .

  A) Cylinder

  B) π * r² * length
