Lesson 14 Student Outcomes

• Students understand that volume is additive and apply volume formulas to determine the volume of composite solid figures in real-world contexts.
• Students apply volume formulas to find missing volumes and missing dimensions.

Lesson 14 Classwork

Example 1
Part A: The area of the base of a sandbox is 9 1/2 ft2. The volume of the sand box is 7 1/8 ft3. Determine the height of the sand box.
Part B: The sand box was filled with sand, but after kids played, some of the sand spilled out. Now the sand is at a height of 1/2 ft. Determine the volume of the sand.
Example 2
A special order sand box has been created for children to use as an archeological digging area at the zoo. Determine the volume of the sand box. Problem Set
1. The volume of a rectangular prism is 21/12 ft3, and the height of the prism is 3/4 ft. Determine the area of the base.

2. The volume of a rectangular prism is 10/21 ft3. The area of the base is 2/3 ft2. Determine the height of the rectangular prism.

3. Determine the volume of the space in the tank that still needs to be filled with water if the water is 1/3 ft. deep.

4. Determine the volume of the composite figure.

5. Determine the volume of the composite figure.

6. a. Write an equation to represent the volume of the composite figure.
