Basics on the topic Volume and Capacity

Join Freddie and Zuri as they learn all about Volume and Capacity.

Volume and Capacity exercise

Would you like to apply the knowledge you’ve learnt? You can review and practice it with the tasks for the video Volume and Capacity.
  • What are volume and capacity measured in?

    Hints

    This tool is used to measure length. Look closely to see the unit.

    Volume and capacity measure liquids. What are liquids measured in?

    Here the volume of water is being measured, can you see the units being used?

    Solution

    Volume and capacity are measured in millilitres and litres (ml or l).

  • Can you complete the definitions?

    Hints

    The capacity of a container is the largest amount it can hold.

    The volume of the liquid in the jug is 60 ml.

    The capacity of this jug is 100 ml.

    Solution

    Volume: How much liquid is in a container.

    Capacity: How much liquid a container can hold.

  • What is the capacity and volume of each of these jugs?

    Hints

    Remember capacity is the total amount of liquid a container can hold.

    Look carefully at the scale to find the volume.

    For example, the capacity of this jug is 100 ml and the volume is 80 ml.

    Remember, there are 1,000 millilitres in 1 litre.

    Solution

    Here we can see the capacity and volume of each jug.

    Remember, the capacity is the total amount of liquid a container can hold and the volume is how much liquid is in a container.

    Therefore, the capacity of the jug on the left with the green liquid is 100 ml as that is the total amount of liquid it can hold. The volume is 30 ml as this is how much liquid is in the jug.

    The capacity of the jug in the middle with the pink liquid is 10 ml as that is the total amount of liquid it can hold. The volume is 7 ml as this is how much liquid is in the jug.

    The capacity of the jug on the left with the green liquid is 1 l or 1,000 ml as that is the total amount of liquid it can hold. The volume is 400 ml as this is how much liquid is in the jug.

  • Which jug should we use for each ingredient?

    Hints

    Look carefully at the capacity of each jug.

    Look carefully at the scale.

    Which liquid does the recipe need most of? This will need the jug with the largest capacity.

    Solution

    The recipe needs 600 ml of water so we need a jug with a capacity that is larger than that, therefore, we use the jug with the 1 l capacity for water.

    The recipe needs 90 ml of blackcurrant juice so we need a jug with a capacity that is larger than that, therefore, we use the jug with the 100 ml capacity for blackcurrant juice.

    The recipe needs 8 ml of lemon juice so we need a jug with a capacity that is larger than that, therefore, we use the jug with the 10 ml capacity for lemon juice.

  • How much juice is in this jug?

    Hints

    We can use the scale to see that the volume is between 50 ml and 100 ml.

    Count up in steps of ten from 50 ml until you reach the line where the juice is.

    Solution

    The volume of the juice in the jug is 80 ml.

  • Which jug should be used for the tropical juice?

    Hints

    Look carefully at the capacity of each jug.

    Add all of the amounts of juice together to find the total volume. Which jug would this fit into.

    450 + 200 + 150 + 50 = 850

    Which jug will be able to hold 850 ml of liquid?

    Remember, 1 litre (l) is equal to 1,000 millilitres (ml).

    Solution

    If we add 450 + 200 + 150 + 50 we get 850.

    The only jug that will hold a volume of 850 ml is the jug with a capacity of 1 l.
