fish tank. They are both cubes. The side length of the

freshwater tank? (1 point)

The volume of a cube is given by V = s^3, where s is the side length.
Volume of the freshwater tank: V_freshwater = 15^3 = 3375 cm^3
Volume of the saltwater tank: V_saltwater = 45^3 = 91125 cm^3
The volume of the saltwater tank is 91125/3375 = 27 times larger than the volume of the freshwater tank.
Therefore, the answer is: 27.
