The number of tropical fish that an aquarium can hold depends on the volume of the fish tank. The interior dimensions of the fish tank below are 28 cm, 49 cm, and 52 cm. Each fish requires 10,000 cubic centimeters of water. How many tropical fish will this fish tank hold?

All you have to do is find the volume of the tank and divide by 10,000.

You'll probably get something that is not divisible by 10,000. Round down because you can't have a fraction of a fish :)

I was told one ince of fish per gallon of the tank

There are 3785.41 cubic centimeters in a gallon. Check it out. :)
