3. 10-1 Space Figures and Nets and Definitions for 10-3
Net – a 2-dimensional pattern that can be folded into a 3-dimensional figure

4. 10-3 Definitions
Polyhedron – a 3-D figure whose surfaces are polygons (flat) Each polygon is called a FACE. An EGDE is where 2 faces meet. A VERTEX is where 3 or more edges meet.

5. Prism – a polyhedron with 2 parallel faces called bases.
Lateral Faces – faces that are not the bases. Altitude – height of prism ( to both bases) Lateral Area – sum of the lateral faces Surface Area – sum of lateral area AND areas of bases

6. Ex 1: Find the lateral Area
LA = sum of areas of rectangles OR LA = ph (perimeter of base*height of prism)

7. Ex 2: Find the surface Area
SA = LA + 2B (lateral area + 2Area of Base)

8. Ex 3: Find the Lateral Area

9. Ex 4: Find the Surface Area

10. Ex 5: Find the Lateral Area

11. Ex 6: Surface Area

12. Cylinder : Like a prism, but has circular bases
Ex 7: Lateral Area

13. Ex 8: Surface Area

14. Ex 9: Lateral Area

15. Ex 10: Surface Area

16. Homework : Worksheet
