Anna Beth has a freshwater fish tank and a saltwater fish tank. They are both cubes. The side length of the freshwater tank is 15 cm. The side length of the saltwater tank is 45 cm. How many times larger is the volume of the saltwater tank than the volume of the freshwater tank? (1 point) Responses 27 27 9 9 3 3 30
The volume of a cube is calculated by V = s^3, where s is 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
The volume of the saltwater tank is 91125/3375 = 27 times larger than the volume of the freshwater tank.
Therefore, the answer is 27.
