Part A: If you increase the length of the box by
4
inches and the height by

Part B: How can the volume of the cardboard box you have built, after you increased the length of the box by
4
inches and the height of the box by
2
inches, be represented?

Part C: When completing a problem that requires multiple operations, explain how you know what operation to perform first.
