How many cubic feet of water to move 50 tons of iceberg?

Answer 1

50 tons of iceberg equals 100,000 lb. It is fresh water, which weighs 62.4 lb/cu ft, so it contains 1603 cu ft of fresh water (imagine a cube, 11'9" on a side), expanded by freezing.

Salt water weighs 64 lb/cu ft, so the iceberg displaces 1563 cu ft while in the ocean.

How much water to float it depends on the size of the vessel it is floating in, and the kind of water used to float the iceberg. I.e. The size of the vessel, minus 1563 for salt water, or minus 1603 for fresh water, equals the amount to float it.

"How [much] ...to move [it]?" has no answer.
