Steps: 1) Calculate the volume of a cylinder of radius 10, and length 2km, and divide by 2. This will give the volume of the semicircular cylinder. 2) Calculate the volume of the dump truck. 3) Divide the volume of the tunnel (semicircular cylinder) by the volume of the truck to find out how many trucks are needed.
