In addition, side B is 8'4" tall as compared with 3'8" high for the remaining 1'2"-thick walls (this is why side B is not included in Fig.2). Calculate the quantity of concrete in exterior foundation walls. 38-10" EDGE OF FOOTING 85'-0" 32-4" 13'-10" EXTERIOR WALL OF THE BUILDING K 40'-0" A N B 32-4" 32-4" 30'-0" P D GRADE BEAM C H G Fig 1.
