## Chapter 11, Lesson 9

Molly and Jan are working with rectangular prisms.

**a.** Find the ratios of the measures of the corresponding edges of the two rectangular prisms. Make an observation about these ratios. Based on your experience with plane figures, how would you describe these two solid figures?

**b.** Find the ratio of the surface areas of the two prisms. Make an observation about the relationship between the ratio of the surface areas and the ratio of the measures of the corresponding edges.

**c. **Find the ratio of the volumes of the two prisms. Make an observation about the relationship between the ratio of the volumes and the ratio of the measures of the corresponding edges.
