📏 Part 1: Understanding Volume and Capacity

1. Circle the correct definition for capacity:

How much space an object takes up

How much a container can hold

The weight of a liquid

The height of a container

2. Which of these are correct? (Check all that apply)

1 mL = 1 cm³

1000 mL = 1 L

Volume measures how much space something occupies

Capacity is only measured in litres

3. Fill in the blanks:

The __________ of a bottle tells us how much liquid it can hold, while the __________ of a box tells us how much space it takes up. We can measure capacity in __________ and __________, and we know that 1 mL equals _____ cm³.

🧮 Part 2: Converting Units

4. Convert these measurements. Show your working:

a) 2500 mL = _______ L

b) 3.5 L = _______ mL

c) 750 cm³ = _______ mL

d) 1.2 L = _______ cm³

5. Order these containers from smallest to largest capacity:

Container A: 1.5 L Container B: 800 mL Container C: 2200 mL Container D: 0.9 L

Smallest: _______ → _______ → _______ → _______ :Largest

📊 Part 3: Estimation and Measurement

6. Look at the containers below and estimate their capacity. Then record your actual measurements:

Container 1 (Water bottle):

My estimate: _______ mL Actual measurement: _______ mL

Container 2 (Measuring jug):

My estimate: _______ mL Actual measurement: _______ mL

Container 3 (Small cup):

My estimate: _______ mL Actual measurement: _______ mL

7. Draw a container and label its estimated capacity:

My container's estimated capacity: _______ mL or _______ L

🧩 Part 4: Problem Solving

8. Sarah has a 2-litre bottle of cordial. She pours out 350 mL for her brother and 275 mL for herself. How much cordial is left in the bottle?

Answer: _______ mL or _______ L

9. A rectangular box has dimensions of 10 cm × 8 cm × 5 cm. What is its volume in cubic centimetres? If this box could hold water, what would its capacity be in millilitres?

Volume: _______ cm³ Capacity: _______ mL

10. Match each measurement with its equivalent:

1. 5000 mL

2. 0.75 L

3. 1500 cm³

4. 2.5 L

A. 750 mL

B. 1.5 L

C. 5 L

D. 2500 mL

🌏 Part 5: Real-World Applications

11. You're helping to cook damper for your class. The recipe calls for 400 mL of water, but you only have a measuring cup marked in litres. How much water do you need to measure?

12. A swimming pool holds 50,000 litres of water. How many cubic metres is this? (Remember: 1000 L = 1 m³)

Answer: _______ m³

13. Explain how understanding volume and capacity helps in everyday life. Give two examples:
