Question

You have a 3 liter and a 5 liter bottle. How do you measure 4 liters of water exactly?

Answer 1

Hey user!

Here's the answer you are looking for

Fill 8, 3ml bottles.

Then pour the water out of the 3ml bottles to 5ml bottles till you fill 4, 5ml bottles.

After you fill 4, 5ml bottles with the water that was initially in 3ml bottles, you will be left with exactly 4ml water in the 3ml bottles.

Hope that makes sense to you.
