3D Surface Area and Volume

Activity Overview

In this TI-84 activity, students will be finding both the Surface Area and Volume of several 3D objects


  • Students will analyze and discuss 3D objects and the 2D shapes that make up those objects.
  • Students will unfold 3D objects to aid in finding both the Surface Area and Volume of the objects.
  • Students will apply this knowledge to finding the Surface Area and Volume of real-world objects.
  • Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments.


  • Circle
  • Circumference
  • Sector
  • Cylinder
  • Surface Area
  • Volume

About the Lesson

Students will work to solve real-world Surface Area and Volume problems. They will also have a chance to practice the unfolding of 3D objects.
