In a road construction, the lenght of economic haul was determine to be at station 100+111 whose area is17.01 square meters and station 100+428 whose area is 23.99 square meters. If the lenght of the free haul distance is 50m, determine the volume of the overhaul in cubic meters. Please take note that the distance from the balance station to both of the two stations are equal. Numerical answer only no units necessary.
