Lesson Purpose

The purpose of this lesson is to expand student's knowledge of using the volume formulas.  Students will use volume formulas to calculate volume of cylinders, cones, and spheres as well as calculate missing dimensions for real-world problems.  Students will use these skills to determine the difference in volume of a rectangular shaped pool and a cylindrical shaped pool.  Also, student will look at the amount of space four ice cubes take up after melting into a cylindrical shaped container.  The ability to use and explain volume formulas is a major work for Level E Geometry.

Students will use many previously learned skills in this lesson in order to calculate volume and the missing dimensions when given volume.  Students will need to have an understanding of substitution and solving equations for a variable.  Students will also need to be familiar with converting units of measure.
