The planned tunnel is 12 meters wide. To allow safe passage for vehicles, the tunnel must be 6 meters high at a distance of 4 meters from the tunnel’s edge. You have to know how many cubic meters of concrete will be used for the tunnel’s side support considering that the straight tunnel is 100 meters long. First, you are to compute the area bounded by the ground and the parabola. Then, use this to compute the volume of what remains of the “prism after removing the parabolic tunnel” to know how much concrete will be needed to fill it. Your computations will also help the cost analyst to accurately compute the overall projected cost of the project and allow the construction firm to better prepare necessary materials, equipment, and manpower to finish the project on time.
