On average, the surface area A of human beings is related to weight W and height H. Measurements on a number of individuals of height 180 cm and different weights (kg) give values of A (m^2) in the following table.
W (kg) 70 75 77 80 82 84 87 90
A (m^2) 2.10 2.12 2.15 2.20 2.22 2.23 2.60 2.30
1. Show that a power law A = aWb fits these data reasonably well. Evaluate the constants a and b and predict what the surface area is for a 95-kg person.
