Surface Area of Triangular Prisms [3]

A guide to support parents as they work with their students with area, surface area, and volume problems.

Set the bases of a conversation on prisms. The segment of a playlist on geometry introduces prisms and their parts. After visualizing prisms, the video discusses how to find the surface area and volume of prisms.

Learn to love the L-shape prism. Viewers of an informative video see how to find the surface area of a composite prism. The method shown finds the area of each side separately and then calculates the sum.

Wrap up a lesson on surface area with a useful video. Pupils learn how to find the surface area of triangular and trapezoidal prisms. They watch a video to see an example for each type of prism.

Give small groups handfuls of unit cubes and then dare them to build as many rectangular prisms as possible using only 12 cubes. This engaging activity serves as an introduction to the volume of solid figures. In addition to volume,...

Not all prisms are cubes. A short video introduces the definition of a prism and uses that definition to create a general volume formula. Worksheets provide pupils several opportunities to practice finding the volume of a wide variety of...

While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they...

In this lesson, you will learn to determine whether to find area, surface area, or volume in a given situation by thinking about what units are needed. [3:38]
