Surface area is the sum of the parts. Given the measurements of different prisms, pupils determine their surface areas. Individuals find the area of each surface and figure out the surface area by finding the sum. The video, part of a review of General Certificate of Secondary Education, reinforces the idea of finding the sum of the areas of the different faces.

Instructional Ideas

• Have the class build different solids and then calculate their surface areas

Classroom Considerations

• Individuals should know how to find the area of rectangles, triangles, and trapezoids
• Class members need to be able to visualize the faces that are not shown in the drawings

Pros

• Shows the different surfaces that comprise the surface area
• Includes all the calculations to arrive at the solution

Cons

• The triangular and trapezoidal prisms in the video are not possible with the given dimensions
