To calculate the volume of a cube, you cube the side length.

For the freshwater tank: 15 cm * 15 cm * 15 cm = 3375 cm^3

For the saltwater tank: 45 cm * 45 cm * 45 cm = 91125 cm^3

Then, divide the volume of the saltwater tank by the volume of the freshwater tank to find out how many times larger it is:

91125 cm^3 / 3375 cm^3 = 27

So, the volume of the saltwater tank is 27 times larger than the volume of the freshwater tank.
