Your math teacher tells you that your fish tank will have his capacity of about 976 cups. Do you have a total of 30 tropical fish. For them to flourish in the fish tank there needs to be an average of 2 gallons of water for each fish 976 cups gallons

To convert cups to gallons, we need to know that 1 gallon is equal to 16 cups.

So, 976 cups is equal to:
976 cups / 16 cups/gallon = 61 gallons

If each fish needs 2 gallons of water, and there are a total of 30 fish, the total water needed for all the fish is:
2 gallons/fish * 30 fish = 60 gallons

Since there is only 61 gallons of water available in the fish tank, it seems like there is just enough water for the fish to flourish.
