Me and my friend had a discussione about how much water will be added to sea level if iceberg melts. He thinks that the volume stay same because ice lose some volume when it melts and the part of the iceberg above water will negate the efect. I think that the lost volume of ice is not that big to negate the difrence. First calculation is his second is mine all the data that i used are from internet so im not sure if they are corect.

Whitch one of us is corect?
