It wouldn't cost 6x as much to have Norwegian standard prisons in the US because prices/salaries are quite a bit lower. Also, the fact that the US if effing huge would mean that economies of scale would bring down the price even further.
On the other hand - widespread poverty to an extent that is completely unknown in Norway - would mean that US prisons can't be too nice, or they would be more attractive than life on the outside. (I don't know if this concern is a real problem, but it's worth mention it)
