For conventional units having nominal heights of 8 in. (203 mm) and nominal lengths of 16 in. (406 mm), the exposed surface area of a single unit in the wall is 8 / 9 ft 2 (0.083 m 2 ). Including a 5 percent allowance for waste and breakage, this translates to 119 units per 100 ft 2 (9.29 m 2) of wall area. (See Table 1 for these and other values.)
