To find the volume of a cube, you cube the side length.
Volume of the freshwater tank = 15^3 = 3375 cm^3
Volume of the saltwater tank = 45^3 = 91125 cm^3
Then, you divide the volume of the saltwater tank by the volume of the freshwater tank:
91125 / 3375 = 27
Therefore, the volume of the saltwater tank is 27 times larger than the volume of the freshwater tank.
