New city. New home. New toilet. One of those pricey Toto jobs. Here’s the question:
You need a puzzle-piece button â€” one of those buttons that’s cut neatly into two buttons. One side flushes out more than the other. The best button design gets an extra-credit contract to manufacture one million of them.
I’d leave it to the student to ask how much each side flushes out: .9 and 1.6 gallons. (Be less helpful, etc.)
Here the question for you, the math-curious blog-reader: which of these buttons is the best design? Essential secondary question: in each case, what question do you ask students to nudge them away from an inferior design to something superior?
Here’s Toto’s answer, which prompts the question: did they get it right?
A: Sort of.
And yeah, this is what happens when I leave the classroom. I blog about bathroom fixtures.
