Even if he can finish the 13th cube, he will only be able to get 2,197, which is only one third of what he can get from combining the first twelve cubes. That's how big of a boost he will get if he can can link the cubes into one layer, forming a net is.
Of course, if he could use the 270 units of commonality to create a 3-dimensional Supreme Metac with a dimension of 135,134,1,(x,y,z), he would be able to get a volume of 18,090, which has the highest volume-to-commonality performance.
Unfortunately, he can't create a Supreme Metac with an indefinite size. He simply doesn't have the knowledge and resources needed to do something like that.
While thinking about the problem, he said, "I also don't have the resources to link the cubes. That incomprehensible material didn't have the information to do so. It only had the schematics."
"I guess that's what I can expect to receive from the piece of origin of another being. I don't even know what an origin is."
