In order to adequately heat or cool a house, a contractor must determine the number of cubic meters of space inside the house. A floor plan of a house with two sections, $$A$$ and $$B$$, is shown above. Each section of the house has a rectangular floor and is shaped like a rectangular solid. Section $$A$$ is $$1$$ story high, section $$B$$ is $$2$$ stories high, and the distance from the floor to the ceiling for each story is $$2.7$$ meters. Disregarding the dimensions of interior walls and structures, approximately how many cubic meters of space are inside the house?
In the circle shown, point $$O$$ is the center, and the length of arc $$ABC$$ is $$12$$. Quantity A The area of the shaded region Quantity B $$144π$$
