Because the marble has a lesser density than water. And also because of the marbles shape and size. :)
No because aircraft carriers are so huge and it can handle lots of punishments. Aircraft carriers are incredibly strong. If you fire one missile at it, it still could float and move even up to twelve missiles and the aircraft carrier will take damages and still can move. If you fire several missiles or more, the whole aircraft carrier will sink.
u See i donβt know but Iβm guessing not
There is no maximum theoretically. As long as the weight of the water being displaced is greater than the weight of the ship itself, it will float. That's why a 1 pound steel ball sinks, but a 90,000 ton aircraft carrier made out of the same material floats.
It should, it's air tight. An Aircraft carrier floats and it's hugh. Any rocket scientists out there?

Draught of vessel + clearance from bottom required + fall of tide (fall = depth of current tide minus depth of next low water)
Iron doesn't float. To float it has to be lighter than water. It is heavier.
it is hollow so it will float
A steel marble will sink because it's solid steel and heavier than water all the way through. A steel ship is hollow and the inside is full of air. Just the shell is heavier than water but, on the whole with the air inside, the ship is lighter than the water so it floats. Experiment: Take an old, empty can (with no lid on it) from the kitchen and submerge it water. It will stay submerged. The can itself is heavier than water. Now fish the can out and empty the water out of it, and put a small weight (maybe a small piece of stone or something) to hold the can upright in the water. The can will now float!
sink
The density of water is roughly 1 gram/cm3. If the density of the substance is less than that, then a solid lump of it can float. Otherwise it can't, but you can form the lump into shapes that can float, just as plate steel is formed into the shape of cruise ship or an aircraft carrier.
