How Many Rockets for a Stone Floor?
4 rockets
4 Rockets destroys a Stone Floor (500 HP), from either side. That's 5,600 sulfur once you count the gunpowder, and about 20s to place.
Timed Explosive Charge is cheaper for this.
2× Timed Explosive Charge costs 4,400 sulfur against 5,600 for 4 Rockets — a difference of 1,200 sulfur per a Stone Floor. If you've already got the Rockets, use them; if you're farming from scratch, don't.
What 4 Rockets costs
These are full craft costs — the sulfur figure includes everything that goes into the gunpowder, which is why it's bigger than the recipe on the item page suggests. Sulfur is the number that actually matters, because it's the thing you farm.

No. Timed Explosive Charge is cheaper on sulfur for this target — 2× costs 4,400 sulfur versus 5,600 for 4 Rockets. That said, cheapest isn't always right: Rockets may be faster to place or already in your base, and sulfur you've already farmed is a sunk cost.

5,600 sulfur, plus 7,800 charcoal and 400 metal fragments. That's the full craft cost including the gunpowder each rocket needs, not just the final recipe.
How long does it take to raid a Stone Floor with Rockets?expand_more
About 20s of placement time for 4 — that's the deploy time, not the farming. The farming is the real cost, and it's why people check this number before they commit.
Amounts come from the same sourced raid chart as our raid calculator and every /raid/ page, so they can't disagree with each other — verified for the Livestock wipe. Deployables and external walls are approximate; always test on your own server build. Sulfur includes the full gunpowder chain.
