Answer:
Bowling ball.
Explanation:
Density of any object may be defined as the mass of an objects per unit the volume covered by the object. The formula to calculate density is mass/ volume.
A bowling ball and a soccer ball both has same volume and size. The density of bowling ball is is higher than soccer ball because the bowling ball has the larger mass than soccer ball. Density of an object is directly proportional to its mass. Hence, the bowling ball has higher density.
Thus, the answer is bowling ball.
