See http://www.jiskha.com/display.cgi?id=1290346564 for explanation of Archimedes principle of floatation.

Basically an object floating in a fluid displaces a volume of fluid equal to its own weight.

So this 1 m³ object has 80% of it submerged. How much weighs the water it displaced? And its own weight equals?
