Formally, here is the answer:
Surface area of a cylinder = [2*pi*radius*height] + [2*pi*(r^2)]
The ends of the cylinder are 8 feet across and the cylinder is 40 feet long, so we have r = 4 and h = 40.
Therefore, SA = (2*pi*4*40) + [2*pi*(4^2)] = (320*pi) + (2*pi*16) = (1005.3) + (100.5) = 1105.8 square feet
However, because the cylinder is open at both ends, you do not include the surface area of the circle at each end of the cylinder.
So the surface area of the cabin is just 1005.3 square feet.
Power always thinks it has a great soul, and vast views, beyond the comprehension of the weak. And that it is doing God's service when it is violating all His laws.

It would not mater if there was swiss cheese on the end. The cylinder. Nothing on the ends would be part of a cylinder. You can put ends on a cylinder but they are not part of the calculation of the cylinder. You can cap a cylinder but the caps are not part of the cylinder. You would calculate them separately.
