1. Investigation 5
Nets

2. A net is a diagram of the faces of a solid so that the diagram can be folded to form the Solid
Which of these figures is not a net for a triangular prism? Why? The top right, because it has one too many lateral faces

3. Draw 2 different nets for a cube
Possible Nets
Not Possible Nets

4. Explain why these cannot be nets for a cube
Figures 1, 2 & 3 will have overlapping faces Figure 4 does not have enough faces 1 2 3 4

5. Common Nets For Prisms
What conclusion can you make nets for all prisms? Hint, what shape does all the lateral faces make? They form one rectangle/parallelogram This will aid us in finding surface area

6. Rectangular/Square Pyramid
Net for a pyramid
Triangular Pyramid
Rectangular/Square Pyramid

7. Net for a pyramid
Pentagonal Pyramid
Hexagonal Pyramid

8. Draw a Net for an octahedron

9. Which one is not a Net for an octahedron?

10. Looking Forward Making nets will for solids will prepare you for:
Lesson 54: Representing Solids
Lesson 59: Finding Surface Area & Volume of Prisms
Lesson 62: Finding Surface Area & Volume of Cylinders
Lesson 70: Finding Surface Area & Volume of Pyramids
