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

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…

### How many gallons does an 18 foot above ground pool hold?

In order to calculate the volume of the pool, the depth must be known. Then the volume must be multiplied by the number of gallons of water per cubic foot. The surface area of an 18-ft-diameter pool is 254.47 sq ft. Multiply that number by the depth (in ft) to find the volume. Then multiply the volume by 7.481 (gallons per cu ft) to find how many gallons the pool will hold. Example, 18-ft-dia pool…
