Representation and explanation
Use Consolidation Questions 1 and 2 above (not two questions of your choice). For Question 1 draw two nonoverlapping cuboids with independent volumes. For Question 2 draw two nonoverlapping cuboids with independent volumes. Label all quantities, include physical measurement units when they are part of the question, show which operation your model proves, and check the answers by an inverse calculation or a size estimate.
