Correct response: 27
Explanation: The ratio of the volumes of two cubes is equal to the ratio of the cubes of their side lengths. In this case, the ratio of the side lengths is 45/15 = 3. Therefore, the ratio of the volumes is 3^3 = 27. This means that the saltwater tank is 27 times larger in volume than the freshwater tank.
