Andre, a physics undergraduate, enters a coffee shop that is holding a contest. Customers who guess the number of coffee beans inside of a closed, 20.0 fl oz20.0 fl oz aluminum commuter mug get a free pastry and an espresso drink. Motivated by the prospect of free food and coffee, Andre puts his finely‑tuned estimation skills to work. Andre assumes that a typical coffee bean is about 1 cm1 cm long. Based on that assumption, what should Andre submit as his estimate for the number of coffee beans in the mug?
