20. To organize the calculation, we introduce the notion of density: ρ = m V . (a) We take the volume of the leaf to be its area A multiplied by its thickness z . With density = 19.32 g/cm 3 and mass m = 27.63 g, the volume of the leaf is found to be V m == 1430 .. cm 3 We convert the volume to SI units: () 3 36 3 1m 1.430 cm 1.430 10 m . 100 cm V §· × ¨¸ ©¹ Since V = Az with z = 1 × 10 -6 m (metric prefixes can be found in Table 1–2), we obtain
