This Instructional Activity is a part of the Lesson 18, Unit 6, Grade 7. In Example 3, make sure students understand that the edges of a slice are determined by the number of faces the slicing plane meets. In other words, there is a correspondence between the sides of the polygonal region formed by the slice and the faces of the solid; the polygon cannot have more sides than there are faces of the solid.
