  3. Musical Math Find the surface area of the following solid. 3 ft 2 ft 2 ft

  4. Cornell Notes Topic: 7-9 Similar Solids Essential Question(s): How do I find the dimensions, surface area, and volume of similar solids?

  5. Questions: Notes: Cornell Notes What are similar solids? Similar Solids – two solids with the exact same shape with all corresponding faces and bases proportional Example: How do I find a missing measure? Write a proportion: A B 3 in 6 in 2 in X

  6. Questions: Notes: Cornell Notes How do I find ratios of surfaces areas for similar solids? Step 1 – Determine the scale factor between the two solids Remember: Scale factor from solid A to Solid B = or Step 2 – Square the scale factor Step 3 – Multiply the result from step 2 by a known area that corresponds to the missing area (X). Example: Assume the SF from pyramid A to B is 2. B A 2 ft2 X

  7. Questions: Notes: Cornell Notes How do I find ratios of volumes for similar solids? Step 1 – Determine the scale factor between the two solids Remember: Scale factor from solid A to Solid B = or Step 2 – Cube the scale factor Step 3 – Multiply the result from step 2 by a known area that corresponds to the missing area (X). Example: Assume the SF from pyramid A to B is 2. B A V = 2 ft3 V = X

  8. Concept Check In your table groups, use a WHITE BOARD to complete the table. B Assume the scale factor from A to B is 3. A x 2 in
