Lesson objective: Apply understanding of adding volume of multiple right rectangular prisms. 

This lesson provides an opportunity for students to apply their knowledge and understanding of adding volume to a real-life situation. Students are asked to decompose blueprints of a swimming pool to find the total volume. Then students will determine the volume of dirt a dumptruck can haul to determine the cost of hauling the dirt removed from the swimming pool. 

Key Concept students will use: 

  • Volume is additive.

Skills students will use:

  • Volume formulas

Students engage in Mathematical Practice 7 (Look for and make use of structure) as they decompose an irregular solid figure into right rectangular prisms to solve for volume. 

Students engage in Mathematical Practice 6 (Attend to precision) as they convert between cubic yards and cubic feet to make mathematical decisions. 

Key vocabulary: 

  • additive
  • capacity
  • decompose
  • volume

Special materials needed:

  • isometric dot paper
  • unit cubes
  • yard stick
