This Problem Set is a part of the Lesson 25, Unit 6, Grade 7. The pieces in Figure 1 are rearranged and put together to form Figure 2. Use the information in Figure 1 to determine the volume of the prism. Use the information in Figure 2 to determine the volume of the prism. If we were not told that the pieces of Figure 1 were rearranged to create Figure 2, would it be possible to determine whether the volumes of the prisms were equal without completing the entire calculation for each?
