When a substance has a density that is less than the density of water, it floats. A wooden sphere has a radius of 4 centimeters and a mass of 250 grams. Will the wooden sphere float? Use the fact that the density of water is 1 gram per cubic centimeter. Round answers to the nearest hundredth. A.  The density of the wooden sphere is 0.93 grams per cubic centimeter, which is less than the density of water, so it will float.   B.  The density of the wooden sphere is 1.24 grams per cubic centimeter, which is greater than the density of water, so it will not float.   C.  The density of the wooden sphere is 0.93 grams per cubic centimeter, which is less than the density of water, so it will not float.   D.  The density of the wooden sphere is 1.24 grams per cubic centimeter, which is greater than the density of water, so it will float.
