In 2011, artist Hans-Peter Feldmann covered the walls of a gallery at the New York Guggenheim Museum with 100,000 one-dollar bills (Fig. P1.48). Approximately how much would it cost you to wallpaper your room in one-dollar bills, assuming the bills do not overlap? Consider the cost of the bills alone, not other supplies or labor costs. FIGURE P1.48

A certain type of rice has an average grain length and diameter of 6 mmmm and 2 mmmm, respectively (assume that a graine has a form of a cylinder). One cup of this rice, after being cooked, contains about 785 food calories. Assume the cup volume is 240 cm3cm3. How many grains are there in 1 cup of rice? Assume perfect packing of the grains of rice (no unoccupied volume in the cup). Express your answer using one significant digit.
