Your class has been assigned to design a fish tank for the fish that you will be getting in your class. There will be four fish, each 3 inches long. Keep in mind that fish tank sizes are usually given in gallons. This excersise will help you gain understanding how to estimate a gallon.
What we are comparing here is the capacity of these containers.
Homework:
1- Research to see if there is a guideline for how many gallons a fish needs to live.
2- What capacity does a gallon have?
You will be shown examples of containers, indicate whether you think the shape will hold less than a gallon, a gallon, or more than a gallon.
