OK, two quetions for the price of one, what a bargain. :-)
Is there an actual mathematical formula for calculating the square root of a number ?? (not using tables)
If the following are true...
1. Icebergs are made of Ice
2. Only the tip of the iceberg is visible (i.e. above the water)
3. Ice has a greater volume that water
4. We worry about global warming and the effect it will have on the sea level
... surely, if an iceberg melts due to global warming, the sea level would drop rather than rise, as the majority of the berg is under-water and therefore the volume of the entire iceberg would decrease
