This Instructional Activity is a part of the Lesson 18, Unit 6, Grade 7. With your group, discuss whether a right rectangular prism can be sliced at an angle so that the resulting slice looks like the figure in Figure 4. If it is possible, draw an example of such a slice into the following prism. Once students have had some time to attempt Example 2, pose the following questions: Is it possible to slice this right rectangular prism to form a quadrilateral cross section? Remember, we are slicing at an angle now. Consider what you know about vertices and the edges they fall on from Example 1.
