  1. Surface Area The sum of the area of all the faces of a polyhedron

  2. Prism • A polyhedron with exactly two congruent, parallel faces called bases. • Any other faces are the lateral faces.

  3. Lateral Area: Sum of the areas of the lateral faces (more than 2 of same shape)

  4. Surface Area: Sum of the lateral area and the two bases.

  6. Find the Surface Area of Each Prism 4 in 3 ft 10 ft 5 in 8 in. 7 ft

  7. Cylinder • Has two congruent parallel bases like a prism, but the bases are circles. • Altitude of a cylinder is the perpendicular segment that joins the bases. • The height (h) of a cylinder is the length of the altitude.

  8. Lateral Area: The area of the “curved surface”. Height of Cylinder Circumference of Circle

  9. the surface area of a cylinder is 2πr2+ (2πr)h FORMULA FOR SURFACE AREA OF A CYLINDER

  10. Find the Surface Area of each Cylinder. 11 in 2 cm 16 in 8 cm

  11. Surface Areas of Pyramid

  12. Find the value of each in order to find surface area Perimeter of Base: Area of Base: Height: Slant Height: 24 14 14

  13. Determine the surface area of the pyramid below

  14. Cone • Pointed like a pyramid, but its base is a circle. • Altitude, of a right cone, is a perpendicular segment from the vertex to the center of the base. • Height (h): the length of the altitude. • Slant Height (s): the distance from the vertex to a point on the edge of the base.

  15. Lateral area: an ice cream cone

  16. Surface Area: the sum of the lateral area and the base(circle) +

  17. Find the surface area of each cone 25 cm 22 in 15 cm 26 in

  18. CREATE A FORMULA CHEAT SHEET RIGHT NOW!!! • SURFACE AREA OF • PRISMS • CYLINDERS • PYRAMIDS • CONES
