week 3 math volume

• Volume


  The amount of space occupied by an object
• Cube


  • Solid figure whose length, width and height are equal
• Rectangular prism


  • Solid figure whose length, width and height may or may not be equal
• Visualizing the volume of a cube

  1. Use standard units to count the number of cubic units needed to fill the space

  2. Volume = side length x side length x side length (V = S³)
• Visualizing the volume of a rectangular prism


  1. Use standard units to count the number of cubic units needed to fill the space

  2. Volume = length x width x height (V = l x w x h)

  
• Volume is expressed in cubic units (unit³)
• Non-standard units do not give consistent and accurate measure of the volume of a container
• Standard units are consistent and accurate for measuring volume
• Volume


  The amount of space an object occupies
• Dimensions of a rectangular prism

  • Length
  • Width
  • Height
• A rectangular prism is a cube when its length, width and height are all equal
• Computing the volume of a rectangular prism

  Multiply the length, width and height
• Volume of a cube


  Side length x Side length x Side length (S³)
