1. Warm-up: A box of Mr. Rob's Super Duper Donut Holes has a volume of 48 in3.
a) What is one possible set of dimensions of the box? What is the surface area of the box?
**Bonus question: What is the minimum surface area, i.e. uses least amount of cardboard, that still satisfies the volume requirement of 48 in3?
2. Lesson 9.2.2 Cross Sections of 3-D shapes

2. Lesson 9.2.2 Cross Sections of 3-D shapes
- Objective: I will experiment with creating cross-sections of rectangular prisms and rectangular pyramids.
- Problems 61 and 62 with your same partner from Friday.
- Take turns cutting cross-sections in your 3-D shapes
- Cross-sections are the INSIDE face of the shape that has been cut
- Trace the resulting cross-section on your paper
- Switch roles. The next partner will re-make the prism and then create another cross-section
- The GOAL is to make as many different types of cross-sections as possible (triangle, square, rectangle, trapezoid, etc.)
Homework: BuzzMath: Cross-sections of 3-D shapes (link in GC)
All data collection for Statistics project should be brought to class tomorrow
