To calculate the total number of observations necessary for 20 per cell, multiply the number of categories in each variable and then multiply by 20. For sex, there are 2 categories (male, female); for region, there are 4 categories (east, west, north, south); and for marital status, there are 4 categories (single, married, divorced, separated). Thus, 2 * 4 * 4 * 20 = 640.
