Kim owns a unique fish aquarium. If the maximum recommended number of fish in the aquarium is 26 that allows for a density of 0.005 fish per cubic centimeter of water, what is the volume of the aquarium in cubic centimeters?
you want to convert fish to volume, so use the conversion factor
1cm^3 = 0.005fish
26fish * 1cm^3/0.005fish = 26/0.005 = 5200 cm^3
