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? please give me the correct answer
A. 9
B. 27
C. 3
D. 30
B. 27
Volume of freshwater tank = (15 cm)^3 = 3375 cm^3
Volume of saltwater tank = (45 cm)^3 = 91125 cm^3
91125 cm^3 / 3375 cm^3 = 27
The volume of the saltwater tank is 27 times larger than the volume of the freshwater tank.
