As wouter says that's not enough information. That only tells you the 
ratio between the distance between camera and building to the distance 
between camera and plane. The planes apparent size is about 3 stories 
which a quick search tells me is about 9m. another quick search tells me 
a f18s wingspan is about 13.5 meters. This would indicate that the 
distance between camera and plane was about 1.5 times the distance 
between camera and building.

So to figure out the actual distance you need to know how far the camera 
was from the building, wouter says that this may be possible from other 
abberations in the image. I've no idea how to calculate this but the 
lines look very straight to me (I think the big vertical through the 
building is within a couple of pixels of being dead straight)which would 
indicate that this picture was taken from a considerable distance.
