In a certain building operation, it was necessary to remove a portion of a hill which was approximately in the shape shown in thw sketch. Lower base is a rectangle; upper base is a right triangle. AB is parallel to DE; and AC is parallel to DG. All face angles at A and D are right angles. Altitude of solid is AD=240ft ; other dimensions are shown in the sketch. Find the amount of earth removed.
