a student makes a scale model of a large aquarium.Her model holds 5 liters of water.The large aquarium holds 5000 liters of water.By what factor can she multiply the dimensions of the model to get the demensions of the large aquarium?

ratio of volumes = 5000 : 5 = 1000 : 1

volumes are proportional to the cubes of the sides, so

10^3 : 1^3 = 1000 : 1

she should use a factor of 10
