the volume of a plastic covered sealed box is 350 cmcube and the box has a mass 500g. will the box float on water or sink in water? what will be the mass of water displaced by the box? |

Answer» Given that volume of a plastic sealed box V = 350 cm^3. Given that mass of the plastic sealed box M = 500 g. We know that Density d = M/V = 500/350 = 1.6 g/cm^3. We know that density of water = 1g/cm^3. Therefore, Density of sealed box is greater than density of water. Hence, it will SINK in water. Now, Mass of the water displaced by the box = volume * density of water = 350 * 1 = 350 g. Hope this helps! |
