A square-based prism is used as the structure for a tunnel. The tunnel itself is a cylinder cut out of this prism. The face of the cylinder being cut out from the tunnel is 3.4 metres in diameter, while the square based prism structure has the following properties: w = 7 metres, and b = 9.4 metres, the outside of the tunnel needs to be painted. Determine the total area of the structure that needs to be painting. considering that one side is placed on the ground and thus cannot be painted. Round to the nearest square metre.
