Initial Volume of water in tank = 60 L Volume of water removed from tank = 40L To find : volume of water left in tank


Final volume if water in tank = volume of water left in the tank

Final volume = Initial volume of water - volume of water removed

Final volume = 60 L - 20 L = 40 L

Hence volume of water left in fish tank = 20 L ( in one significant figure)

volume of water left in the fish tank = 20 L
