• Volume is the amount of space a solid figure occupies
• Non-standard units


  Units or objects like marbles, stones, beans, etc. that are countable and used to measure volume
• When non-standard units are small, many objects are needed to fill a container, and when they are big, fewer objects are needed
• Non-standard units do not give consistent and accurate measurement of the volume of a container
• Rectangular prism


  A solid figure that has six faces, 12 edges, and 8 vertices
• Vertex/Vertices


  The corner of a shape
• Edge


  A segment where two faces of a prism meet
• Volume formula for a rectangular prism

  Volume = Length x Width x Height
• Volume formula for a cube

  Volume = Side x Side x Side
• Visualizing and finding the volume of a solid figure

  1. Use non-standard units like marbles, beans, etc. to visualize the volume

  2. Use standard units like cubic centimeters and cubic meters to find the volume
