Choose the proper unit of capacity for each object: litre or millilitre.

Let's solve this step-by-step by matching each object with the most appropriate unit of capacity: litre (L) or millilitre (mL).

We need to understand the difference:
- 1 litre = 1000 millilitres
- Litres are used for larger volumes (like bottles, jugs, containers).
- Millilitres are used for smaller volumes (like small bottles, medicine, etc.).

Now, let’s go through each item:

---

1. Milk (carton)

- A typical milk carton is usually 1 litre or 2 litres.
- This is a large container.
✔ Answer: Litre

---

2. Can (soda can)

- A standard soda can holds about 330 mL or 355 mL.
- This is a small volume.
✔ Answer: Millilitre

---

3. Pitcher

- A pitcher is used to hold liquids like water or juice and typically holds 1–2 litres.
- It’s large enough to be measured in litres.
✔ Answer: Litre

---

4. Backpack

- A backpack doesn’t contain liquid, but if we're imagining how much liquid it could carry (e.g., water bottles), it might hold several litres.
- But since it's not a container for liquids, it's more of a trick question.
- However, in context, it's likely meant to represent how much liquid it could hold, so we consider larger capacity.
✔ Answer: Litre (as it could hold multiple litres)

---

5. Hand Soap Dispenser

- These are usually small, holding around 250 mL to 500 mL.
- Not enough for a full litre.
✔ Answer: Millilitre

---

6. Jug

- Similar to a pitcher, a jug holds a significant amount of liquid — often 1 litre or more.
✔ Answer: Litre

---

7. Large Water Bottle

- "Large" implies more than a regular bottle (e.g., 1.5 L or 2 L).
- Definitely measured in litres.
✔ Answer: Litre

---

8. Juice Box

- A juice box is typically 200 mL to 250 mL.
- Small size.
✔ Answer: Millilitre

---

✔ Final Answers:

| Object | Correct Unit |
|----------------------|------------------|
| Milk | Litre |
| Can | Millilitre |
| Pitcher | Litre |
| Backpack | Litre |
| Hand Soap Dispenser | Millilitre |
| Jug | Litre |
| Large Water Bottle | Litre |
| Juice Box | Millilitre |

---

📌 Summary:

- Use Litres for larger containers: milk, pitcher, backpack, jug, large water bottle.
- Use Millilitres for smaller ones: can, hand soap dispenser, juice box.
