It's the parts that make the whole. Learners apply volume formulas to composite figures to find the total volume of the figure. Previous lessons in this series taught the methods for finding the volume and/or dimensions of three-dimensional objects. Now scholars put those concepts together to work with the composite figures.

Instructional Ideas

• Expect scholars to draw and label dimensions of each figure before making calculations

Classroom Considerations

• Video requires Internet access
• Pupils should be proficient with using the volume formulas of spheres, cylinders, and cones

Pros

• Uses context throughout the video and problem set to give learners a frame of reference
• Provides an answer key for the practice problems

Cons

• Practice worksheet does not provide enough room for drawing the figures and showing calculations
