hes areaThe specific gravity of cast iron being 7.110 the weight,of a cubic foot of cast iron will equal 7.110 X 62.5 = 444.3750 1b. CIRCULAR MEASURE 243 And since a cubic foot weighs 444.3750 pounds, a cubicinch will equal 444.3750 + 1728 = .257 lb. Then, since one cubic inch equals .257, the… … Fig. 56 3 feet 6 inches = 42 inches.5 feet = 60 inches.4 feet = 48 inches. First find the area in cubic inches of whole piece. Then find the area of the whole, and subtract the latterfrom the former, and the answer will be the area in cubicinches of iron in the plate. Then multiply the area thus…
