33. The metric prefixes (micro ( µ ), pico, nano, …) are given for ready reference on the inside front cover of the textbook (see also Table 1–2). The surface area A of each grain of sand of radius r = 50 m = 50 × 10 6 m is given by A = 4 π (50 × 10 6 ) 2 = 3.14 × 10 8 m 2 (Appendix E contains a variety of geometry formulas). We introduce the notion of density, / mV ρ = , so that the mass can be found from m = V , where = 2600 kg/m 3 . Thus, using V = 4 r 3 /3, the mass of each grain is () 3 6
