Explanation

Choice A is correct. It's given that the object has a mass of 168 grams and a volume of 24 cubic centimeters. Dividing the mass, in grams, of the object by the volume, in cubic centimeters, of the object gives the density, in grams per cubic centimeter, of the object. It follows that the density of the object is 168 grams24 cubic centimeters, which is equivalent to 16824 grams per cubic centimeter, or 7 grams per cubic centimeter.
