## Stuff It!

#### Activity Overview

Students learn to calculate volume of a sphere and a rectangular prism. They explore methods of determining how many volleyballs can be placed in a room.

#### Before the Activity

• Review the formulas for computing attributes of circles, spheres, and rectangular prisms
• See the attached PDF file for detailed instructions for this activity
• Print pages 109 - 110 from the attached Student PDF file for the class
• #### During the Activity

Distribute the pages to the class.

• Measure the length, width, and height of the room
• Compute the volume of the room
• Use the formula to calculate the volume of the volleyball
• Divide the volume of the room by the volume of the ball
• Determine the number of volleyballs the room can accommodate
• Find the total cost incurred in filling the room with balls, given the price of one ball
• Discuss other methods that can be used to solve the problem and which method will give an under-estimate and which method will give an over-estimate
• #### After the Activity

Students complete the Student Activity pages.

• Review student results
• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
