The volume of the yellow object is not 29cm3 and it is also not 57.4cm3. The white object has a greater mass than the pink object The gray object has a density of 1.349 grams per cubic cm and a mass of 76.9g The density of water is 1.0 grams per cubic cm. If the white object was placed in water, it would sink. The density of water is 1.0 g/cm3. If the yellow object was placed in water, it would float. The density of aluminum is 2.7 g/cm3. The violet object is more dense than aluminum One object has a volume of 57.4 cm3 and a density of 0.5 grams per cubic centimeter. The volume of the violet object is not 11.6 cubic centimeters
