Primary 5 Mathematics Quiz - Measurement (Answer Key)

Total Marks: 40
Topic: Measurement (length, mass, capacity, volume, unit conversion)

Section A (1 mark each)

1. 3000 m
Method: 1 km = 1000 m, so 3 km = 3 × 1000 = 3000 m.

2. 4.5 kg
Method: 1000 g = 1 kg, so 4500 g = 4500 ÷ 1000 = 4.5 kg.

3. 2300 ml
Method: 1 ℓ = 1000 ml, so 2 ℓ = 2000 ml. Add 300 ml → 2300 ml.

4. 72 mm
Method: 1 cm = 10 mm, so 7.2 cm = 7.2 × 10 = 72 mm.

5. 5040 g
Method: 1 kg = 1000 g, so 5 kg = 5000 g. Add 40 g → 5040 g.

6. 2 min
Method: 60 s = 1 min, so 120 s = 120 ÷ 60 = 2 min.

7. 24 cm³
Method: Volume = length × width × height = 4 × 3 × 2 = 24 cm³.

8. 6 ℓ
Method: 1000 cm³ = 1 ℓ, so 6000 cm³ = 6000 ÷ 1000 = 6 ℓ.

9. 80 cm
Method: 1 m = 100 cm, so 0.8 m = 0.8 × 100 = 80 cm.

10. 180 min
Method: 1 hour = 60 min, so 3 h = 3 × 60 = 180 min.

Section B (2 marks each)

11. 3000 cm³
Working: Volume = 20 × 15 × 10 = 3000 cm³.
Marks: 1 for formula, 1 for correct answer.

12. 6 cups
Working: 1.5 ℓ = 1500 ml. 1500 ÷ 250 = 6.
Marks: 1 for conversion, 1 for division.

13. 120 cm³
Working: Volume = base area × height = 24 × 5 = 120 cm³.
Marks: 1 for method, 1 for answer.

14. 240 cm
Working: 1 m = 100 cm, so 2.4 m = 2.4 × 100 = 240 cm.
Marks: 1 for conversion, 1 for answer.

15. 5 cm
Working: Height = Volume ÷ (length × width) = 120 ÷ (6 × 4) = 120 ÷ 24 = 5 cm.
Marks: 1 for method, 1 for answer.

16. 6 glasses
Working: 3 ℓ = 3000 ml. 3000 ÷ 500 = 6.
Marks: 1 for conversion, 1 for division.

Section C (3 marks each)

17. 9 ℓ
Working:
Step 1: Volume = 30 × 20 × 15 = 9000 cm³. (1 mark)
Step 2: Convert to litres: 9000 cm³ = 9000 ÷ 1000 = 9 ℓ. (1 mark)
Step 3: Final answer stated with unit. (1 mark)
Teaching note: 1 cm³ = 1 ml, 1000 ml = 1 ℓ.

18. 216 cm³ = 216 ml
Working:
Step 1: Volume of cube = 6 × 6 × 6 = 216 cm³. (1 mark)
Step 2: Since 1 cm³ = 1 ml, volume = 216 ml. (1 mark)
Step 3: Answer with both units. (1 mark)

19. 1700 ml
Working:
Step 1: 2.5 ℓ = 2500 ml. (1 mark)
Step 2: 2500 − 800 = 1700 ml. (1 mark)
Step 3: Answer with unit. (1 mark)
Common mistake: forgetting to convert ℓ to ml before subtracting.

20. 4000 cm³ = 4 ℓ
Working:
Step 1: Volume = 50 × 10 × 8 = 4000 cm³. (1 mark)
Step 2: Convert: 4000 cm³ = 4000 ÷ 1000 = 4 ℓ. (1 mark)
Step 3: Answer with both units. (1 mark)
