So is it the volume of water risen (Area of 400mm diameter x 30mm) minus 200x200xV(cube submerged)? Problem is, how do I know the V(cube submerged) if I don't have its density?
I'm thinking, calculate V(water displaced) -> calculate mass -> get density.
Thanks voko
Homework Statement
A plastic cube, 200mm x 200mm x 200mm, is left in a cylindrical container that has a diameter of 400mm holding sea water, density 1024kg/m^3. The level in the container increases by 30mm as the block floats.
i) Find the mass and density of the cube.
ii) Find the extra...
