This Instructional Activity is a part of the Lesson 15, Unit 5, Grade 8. In this activity, students use the relationship that the volume of a cone is 1/3 of the volume of a cylinder to calculate the volume of various cones. Students start by watching a video (or demonstration) that shows that it takes the contents of 3 cones to fill the cylinder when they have congruent bases and equal heights. Students use this information to calculate the volume of various cones and cylinders.
