I needs to pour 2 gallons of water into his fish tanks. All he has is a measuring cup how many cups of water should he put in the tank? Explain?

32 cups of water is needed to fill a 2 gallon water tank.

Step-by-step explanation:

Here, the amount of water to be filled in the fish tank = 2 gallons

The utensil to measure water = a measuring cup

Now, as we know:

1 quart = 0.25 gallons

⇒ 4 pints = 1 gallons

⇒ 8 pints = 2 gallons

Also, 1 pint = 0.5 quart

⇒ 2 pints = 1 quarts

⇒ 8 pints = 4 quarts

⇒ 16 pints = 8 quarts

Again, 1 cup = 0.5 pint

⇒ 2 cup = 1 pint

⇒ 32 cup = 16 pints

Hence, 32 cups of water is needed to fill a 2 gallon water tank.
