To find out how much water Fahim should mix, we need to subtract the amount of orange concentrate he already has from the desired total volume of the drink.

Step 1: Convert 3.56 liters to milliliters (since the given amount of orange concentrate is in milliliters).
1 liter = 1000 milliliters, so 3.56 liters = 3.56 x 1000 = 3560 milliliters.

Step 2: Subtract the amount of orange concentrate from the desired total volume.
3560 ml - 67 ml = 3493 ml.

Therefore, Fahim should mix 3493 ml of water to make 3.56 liters of the orange drink for his party.
