Correct response: 27
Explanation:
The volume of a cube is calculated by V = s^3, where s represents the side length of the cube.
For the freshwater tank: V = 15^3 = 3375 cm^3
For the saltwater tank: V = 45^3 = 91125 cm^3
To find out how many times larger the volume of the saltwater tank is compared to the freshwater tank, we divide the volume of saltwater tank by the volume of the freshwater tank: 91125 cm^3 / 3375 cm^3 = 27.
Therefore, the volume of the saltwater tank is 27 times larger than the volume of the freshwater tank.
