If a cylinder is cut into three sections along the plane parallel to the bottom, the surface area will increase by 50.24 square centimeters. If cut along the diameter into two half cylinders, the surface area would increase by 40 square centimeters. If it is cut into several equal parts and assembled into an approximate cuboid, what is the volume of the cuboid in cubic centimeters?
