Looks like ...
... a lot of cloth for a pair of knickers the celebutards are wearing (presumably, since I've never met them, neither the celebutards, nor the knickers...)

The question is: how did they calculate this? 11 metres on a flat surface?
As we all know, Mars isn't flat. Olympus Mons is 26 km high! And the largest of the canyons (or canals in the good old days) is 4000 km long and has a maximum depth of 7 km.
If these canyons fill up (as well as all the impact craters), how much water is left to 'swamp' the planet?
