> detonate 10 bombs side by side and you increase the radius by 10x

By 10**.5~=3.2x

It’s not very tidy phrasing, but I think the meaning is that 10 detonations next to each other (blast diameters touching) is 10x the diameter?

He's right. You'd want to arrange them in a square for comparable coverage so it'd be sqrt(10) = ~3.2.

It feels somehow nice and correct that an effort to reduce a 3d problem (basically a lot of our boom goes up or down, which is not necessary in most cases) to a 2d one changes it from a gain of x^(1/3) to x^(1/2).

The OP presumably meant a line of blasts though? That would possibly be the least efficient orientation after blasting the same spot 10x.

		Depends on your goal, the nature of the target, and how much damage you want to do. At one extreme there are precision attacks in silos and airfields. At the other are genocide attacks where you want to kill as many people as possible and leave as much of the land uninhabitable for as long as possible. In the middle are precision strategic attacks, where you want to leave infrastructure and buildings so you have the option to invade and take over.
