Answers
Primary 4 Mathematics Quiz - Measurement (Answer Key)
Total Marks: 40
Section A: Multiple-Choice Questions (10 × 1 mark = 10 marks)
1. C) metres (m)
Explanation: A classroom is typically several metres long. Millimetres and centimetres are too small for measuring room dimensions, while kilometres are used for much longer distances (like between towns).
2. B) 3,450 m
Working: 3 km = 3 × 1,000 m = 3,000 m. 3,000 m + 450 m = 3,450 m.
3. C) 5,200 g
Working: 5 kg = 5 × 1,000 g = 5,000 g. 5,000 g + 200 g = 5,200 g.
4. C) 24,000 cm³
Working: Volume = length × breadth × height = 40 cm × 30 cm × 20 cm = 24,000 cm³.
5. C) 2,500 mL
Working: 1 litre = 1,000 mL. 2.5 litres = 2.5 × 1,000 mL = 2,500 mL.
6. B) 5 kg 200 g
Working: 3 kg 750 g + 1 kg 450 g = (3 + 1) kg + (750 + 450) g = 4 kg + 1,200 g = 4 kg + 1 kg 200 g = 5 kg 200 g.
7. A) 850 mL
Working: 1.2 litres = 1,200 mL. 1,200 mL − 350 mL = 850 mL.
8. C) 12 cm
Working: Perimeter of square = 4 × side length. Side length = 48 cm ÷ 4 = 12 cm.
9. C) 375 cm²
Working: Area = length × breadth = 25 cm × 15 cm = 375 cm².
10. C) A large water bottle
Explanation: A teaspoon holds about 5 mL, a cup holds about 250 mL, a large water bottle typically holds about 1 litre (1,000 mL), and a swimming pool holds thousands of litres.
Section B: Short-Answer Questions (10 × 2 marks = 20 marks)
11. 7,085 m
Working: 7 km = 7 × 1,000 m = 7,000 m. 7,000 m + 85 m = 7,085 m.
Common mistake: Writing 785 m (forgetting that 7 km = 7,000 m, not 700 m).
12. 4 kg 350 g
Working: 4,350 g ÷ 1,000 = 4 remainder 350. So 4 kg 350 g.
Alternative: 4,000 g = 4 kg, leaving 350 g.
13. 3,000 cm³
Working: Volume = base area × height = 120 cm² × 25 cm = 3,000 cm³.
Note: Base area already given, so no need to calculate length × breadth separately.
14. 4 kg 200 g
Working: Total mass = 12 kg 600 g = 12,600 g. Mass of one box = 12,600 g ÷ 3 = 4,200 g = 4 kg 200 g.
Alternative: 12 kg ÷ 3 = 4 kg; 600 g ÷ 3 = 200 g.
15. 0 m 85 cm (or 85 cm)
Working: 3 m 40 cm = 340 cm. 340 cm ÷ 4 = 85 cm = 0 m 85 cm.
Common mistake: Dividing 3 m and 40 cm separately (3 m ÷ 4 = 0.75 m, 40 cm ÷ 4 = 10 cm → incorrect).
16. 2,150 mL
Working: 2.8 litres = 2,800 mL. 2,800 mL − 650 mL = 2,150 mL.
17. 12 cm
Working: Area = length × breadth. Breadth = Area ÷ length = 180 cm² ÷ 15 cm = 12 cm.
18. 256 cm²
Working: Perimeter = 64 cm. Side = 64 cm ÷ 4 = 16 cm. Area = side × side = 16 cm × 16 cm = 256 cm².
19. 0 kg 950 g (or 950 g)
Working: Total used = 1 kg 750 g + 2 kg 300 g = 4 kg 50 g = 4,050 g.
Total bought = 5 kg = 5,000 g.
Left = 5,000 g − 4,050 g = 950 g = 0 kg 950 g.
Alternative: 5 kg − 4 kg 50 g = 4 kg 1,000 g − 4 kg 50 g = 950 g.
20. 500 m³
Working: Volume = length × breadth × height = 25 m × 10 m × 2 m = 500 m³.
Total: 40 marks
General Marking Notes:
- Accept answers in equivalent forms (e.g., 85 cm or 0 m 85 cm).
- Deduct ½ mark for missing or incorrect units in Section B where units are required.
