ocr: DENSITY AND FLOATING STEEL BLOCK. DISPLACED WATER- STEEL BOAT - - - J - - - , - - - - - - WEIGHT. UPTHRUST. WHETHER AN OBJECT floats in itisdenser than water. Although water or not depends on its a steel boat may weigh the same density. If an object weighs more as the block, iti is. less dense than its own volume of water, because it contains a large that is to say ifit is denser than volume ofair. Because the boat's water, it will sink. A block of overall density is less than that of steel, for example, sinks because water, it will float.
