Imagine filling the box at the right with cubes that are 1 cm \times 1 cm \times 1 cm like the one shown. Explain how filling the box with cubes can be used to make sense of the volume equation for a rectangular prism $-V=a \cdot b \cdot c$.

At Bobbi's Baby Bargains, they make and sell baby blocks in sets of 24 blocks. Bobbi has asked you to design a box to package these blocks that will require the least amount of cardboard. What is your recommendation? Provide a justification as to why your design is the most efficient..

When carpet is purchased for a room, a salesman might ask, “How many yards do you need?” When ordering concrete to pour a sidewalk, the dispatcher will ask, “How many yards do you need?” Are yards in both of these situations the same? Explain
