I'm really new to integration by parts, and unfortunately I am having to learn it out of a book for now. I sort of get the idea, but this one just doesn't look...
Alright... well I think I'm correct in saying something floats when its weight is equal to the weight of the displaced fluid (in this case fresh water). So I've figured out that the volume of ice floating above the water is 0.0734m3, than the total volume of the block of ice can equal 0.0734m3+...
