5. OBJECTIVE 7.G.1 Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

7. CHANGING DIMENSIONS Recall that similar figures have proportional side lengths. The surface areas of similar three-dimensional figures are also proportional. To see this relationship, you can compare the areas of corresponding faces of similar rectangular prisms.

12. The surface Area of a box is 10.4 cm 2. What is the surface area of a similar box that is larger by a scale factor of 3?

13. Formula surface area = surface area x (scale factor) 2 of figure b of figure a (new figure) (old figure)

14. The surface Area of a box is 10.4 cm 2. What is the surface area of a similar box that is larger by a scale factor of 3? Formula surface area = surface area x (scale factor) 2 of figure b of figure a (new figure) (old figure) ______ = 10.4 x 3 2 New figure would be 93.6cm 2 **keep units the same

15. THE VOLUME OF AN ICE CHEST IS 2,160 IN. WAH IS THE VOLUME OF A SIMILAR ICE CHEST THAT IS LARGER BY A SCALE FACTOR OF 2.5?

16. Formula Volume = volume x (scale factor) 3 of figure b of figure a (new figure) (old figure)

17. THE VOLUME OF AN ICE CHEST IS 2,160 IN. WAH IS THE VOLUME OF A SIMILAR ICE CHEST THAT IS LARGER BY A SCALE FACTOR OF 2.5? Formula Volume = volume x (scale factor) 3 of figure b of figure a (new figure) (old figure) ______ = 2,160 x 2.5 3 New figure would be 33,750in 3 **keep units the same

18. REMINDERS When doing area (including surface area), keep in mind it is a 2 dimensional shape. Therefore, you use a square your scale factor. **give it an exponent of 2 When doing volume, keep in mind it is a 3 dimensional shape. Therefore, you use a cube your scale factor. **give it an exponent of 3
