- Jake has two books on his desk. Book A is thicker than Book B, but Book B is longer and wider than Book A. His teacher asks him to name different ways the books can be measured. What is the BEST list of measurable attributes for both books?
Answer: How long, how wide, how thick, and how heavy each book is compared to the other
Choice C is correct because length, width, thickness, and weight are all measurable attributes that can be quantified with numbers and units for physical comparison.

Choice B is wrong because subject, language, and color are not measurable attributes in the mathematical sense. Choice D is wrong because location, publication date, and authorship are not measurable physical attributes.
