mass of One way of restating Archimedes' Principle is that the mass of a block that is floating in a fuid is equal to the the fluid displaced by the block. Imagine that we have a solid block in which all of the sides are 1 cm long-a cube with a volume of 1 cm (Fig.A1.4.2A). We set it in a beaker of pure water and find that, when the block and water come to rest, 70% of the block...
