  1. 11-7 Areas and Volumes of similar solids To compare and find the areas and volumes of similar solids. Students will analyze the relationship between the scale factor, surface area, and volume of similar three-dimensional geometric figures by relating them to rectangular prisms.

  2. 11-7 Quiz • The following questions are designed to help you decide how well you understood today’s lesson. • Be sure to record the number you get right on your portfolio sheet and ask if you miss one!

  3. 1. Are the two figures similar? If so, give the similarity ratio of the smaller figure to the larger figure. • Yes; 1:3 • Yes; 1:2 • Yes; 1:5 • No Non-Response Grid

  4. 2. Find the similarity ratio of a cube with volume 729 m3 to a cube with volume 3375m3 . • 81 : 225 • 3 : 5 • 5 : 3 • 225 : 81 Non-Response Grid

  5. 3. Find the similarity ratio of a prism with surface area 36 ft2to a similar prism with surface area 225 ft2. • 216 : 3375 • 3375 : 216 • 5 : 2 • 2 : 5 Non-Response Grid

  6. 4.The volumes of two similar solids are 729 m3 and 125 m3. The surface area of the larger solid is 324 m2. What is the surface area of the smaller solid? • 56 m2 • 500 m2 • 100 m2 • 200 m2 Non-Response Grid

  7. 5. A glass vase weighs 0.17 lb. How much does a similarly shaped vase of the same glass weigh if each dimension is 6 times as large? • 36.72 lb • 1.02 lb • 220.32 lb • 6.12 lb Non-Response Grid

  8. Assignment 11-7 P. 746-748 #6-38 even Be sure to RATE your understanding of the lesson 4-3-2-1-0 after you finish it AND give me one complete sentence as to why you rated yourself that way then summarize what the lesson was about in a sentence or two.
