You can do whatever you like.
Tell us how you'd do it today and how you'd have done it back then(say 1000 years back).
You vanished, so i answered it myself. In light of that...
Why not give us both?
No, I'm not trying to apply this problem to the pyramids.
Your original answer about building the structure around the cuboid is invalid since I am telling you that in the location where this work was carried out, these blocks where left blocking corridors. It is clear that where they were left was not their final destination. And as such...if the engineers had placed these blocks, then built corridors that blocked themselves off, it would make no sense. Unless they were complete idiots that build immovable lockages into their walkways. Also, the blocks that were left in corridors where clearly being moved to the focal points where the blocked corridors terminate. These focal points were empty, while other focal points already have identical blocks installed.
So I'm not sure how of this was in Egypt, India or Hillbrow, it makes any difference. Like, how if it was Egypt it automatically means the corridors were built around the blocks.
Hence the very clear...
"You wish to move a rectangular cube from one end of the corridor to the other."
You are the one confusing yourself by wandering away from the question. Do i need to state the planet's gravity values, that there weren't TRex benching midgets available and that the blocks were not sentient and self propelling?
Now really, you are just playing dumb and trying to find faults in the question.
Why not just solve the problem.
A) as it was a few thousand years back, and or...
B) with modern technology.
One last time...
You wish to move a 150ton block 100m from one end of a corridor to another. You have all the necessary dimensions.
Try, it or don't try it, but for heaven's sake, stop pretending the task isn't clear.
