High school students were asked the following question, which requires that they understand the Pythagorean Theorem and know how to apply it in three- dimensional objects. But New York state educators question whether students have been taught to solve such complex problems.
A straw is placed into a rectangular box that is 3 inches by 4 inches by 8 inches, as shown in the accompanying diagram. If the straw fits exactly into the box diagonally from the bottom-left-front corner to the top-right-back corner, how long is the straw, to the nearest 10th of an inch?
