You are feeling a 5 L fish tank using 250 mL container. How many full containers are required to fill the fish tank

There are 20 full containers required to fill the fish tank.

To figure this out, we will first convert the fish tank capacity from liters to milliliters, since the container is measured in milliliters.

1 liter is equal to 1000 milliliters, therefore, a 5 liter fish tank is equal to 5000 milliliters.

Next, we will divide the fish tank capacity by the capacity of the container:

5000 mL ÷ 250 mL = 20

So, you will need 20 full containers to fill the 5 liter fish tank.
