A new exhibit hall at a convention center has a floor bounded by x = 0, x = 200, y = -300 +0.01x, and y = 300 -0.01x The ceiling lies on the graph of C(x,y) = 50-0.15x (Each unit on the x, y, and z axes represents one foot.) Find the volume of the exhibit hall (in cubic feet). The volume of the exhibit hall is cubic feet. (Simplify your answer.)
