An object in the shape of a cube has a mass of 375 grams and a side that measure 5.0 cm. Will this object float in water? Prove your answer by comparing the density of the cube to that of water.
Calculate the density of the object. density = mass/volume. You have the mass, the volume of a cube is side^3 so that is 5^3 or 125 cm^3. If the density is greater than the density of water it will sink; otherwise, it will float.
