  2. Using a Net • What is a net? • A two-dimensional pattern that you can fold to make a three-dimensional figure. • Let’s Look

  3. Surface Area • Definition: the sum of the areas of the faces of a shape.

  4. Surface Area of a Triangular Prism

  5. Surface Area of a Triangular Prism #2 9in 6in 4in 7in

  6. Find the total surface area of this shape 5ft 6ft2 Warm-Up 6ft2 48 ft2 15ft2 4ft 12ft2 3ft 3ft 9ft2

  7. Formula for Area of Triangular Prism: SA = wh + lw + lh + ls

  8. Formula for Surface Area of Triangular Prism: SA = wh + lw + lh + ls Find the surface area of a triangular prism with the following dimensions: w = 10cm l = 6cm h = 8cm s = 5cm

  9. Formula for Surface Area of Triangular Prism: SA = wh + lw + lh + ls Find the surface area of a triangular prism with the following dimensions: w = 3in l = 4in h = 6in s = 2in

  10. Surface Area of a Rectangular Prism

  11. Surface Area of a Rectangular Prism # 2 5in 6in 5in

  12. Find the total surface area of this shape Warm-Up 5m 5m 5m

  15. Find the total surface area of this shape Warm-Up 50ft2 10ft 50ft2 15ft2 190 ft2 15ft2 30ft2 3ft 5ft 30ft2

  16. Surface Area of a Rectangular Prism = 2(wh+ lh+ lw) Find the surface area: w = 3in l = 4in h = 6in

  17. Surface Area of a Rectangular Prism = 2(wh+ lh+ lw)

  18. Surface Area of a Cylinder:SA: 2 + • In other words: • Area of the circle (there are two circles). • Area of rectange length × width (height) × (cirumference)

  19. Surface Area of Cylinders

  20. Surface Area of Cylinders 7in 8in

  23. Surface Area of a Cylinder:SA: 2 + • Find the surface area of the cylinder: h = 12in d = 6in

  24. Surface Area of a Cylinder:SA: 2 + • Find the surface area of the cylinder: h = 8cm d = 4cm

  25. Quick Check (I’m collecting this!!) • Pg. 445 in book • Numbers 5, 7, 15 • NO HOMEWORK! 
