Answer 1

Correct response:

27

Explanation: The volume of a cube is calculated by (side length)^3.

Volume of freshwater tank = (15 cm)^3 = 3,375 cm^3
Volume of saltwater tank = (45 cm)^3 = 91,125 cm^3

Volume of saltwater tank / Volume of freshwater tank = 91,125 cm^3 / 3,375 cm^3 = 27

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