Primary 6 PSLE Mathematics Quiz - Measurement (Answer Key)

Total Marks: 40
Topic: Measurement (syllabus-first; no past-paper evidence used)

---

Section A (1 mark each)

Q1. 3500 m
Method: 1 km = 1000 m, so 3.5 × 1000 = 3500 m.
Teaching note: To convert km to m, multiply by 1000.

Q2. 2.5 m
Method: 100 cm = 1 m, so 250 ÷ 100 = 2.5 m.
Common mistake: Writing 0.25 m (forgot ÷100).

Q3. 2300 g
Method: 1 kg = 1000 g, so 2 kg = 2000 g; 2000 + 300 = 2300 g.

Q4. 1200 mL
Method: 1 L = 1000 mL, so 1.2 × 1000 = 1200 mL.

Q5. 24 cm³
Method: V = l × w × h = 4 × 3 × 2 = 24 cm³.

Q6. 125 cm³
Method: Cube volume = edge³ = 5 × 5 × 5 = 125 cm³.

Q7. 80 cm³
Method: V = base area × height = 20 × 4 = 80 cm³.

Q8. 43.96 cm
Method: C = 2πr = 2 × 3.14 × 7 = 43.96 cm.

Q9. 314 cm²
Method: A = πr² = 3.14 × 10² = 3.14 × 100 = 314 cm².

Q10. 1.5 h
Method: 60 min = 1 h, so 90 ÷ 60 = 1.5 h.

---

Section B (2 marks each)

Q11. 6 cm
Method: V = l × w × h → 120 = 5 × 4 × h → 120 = 20h → h = 120 ÷ 20 = 6 cm.
Marking: 1 m for correct equation, 1 m for answer.

Q12. 7 cm
Method: Edge = ∛343. Since 7 × 7 × 7 = 343, edge = 7 cm.
Marking: 1 m for cube root idea, 1 m for answer.

Q13. 9 L
Method: Volume = 30 × 20 × 15 = 9000 cm³. 9000 ÷ 1000 = 9 L.
Marking: 1 m for cm³, 1 m for L conversion.

Q14. 43.96 cm
Method: C = πd = 3.14 × 14 = 43.96 cm. (r = 7, d = 14)
Marking: 1 m for diameter, 1 m for answer.

Q15. 30.84 cm
Method: Half circumference = πr = 3.14 × 6 = 18.84 cm. Diameter = 12 cm. Perimeter = 18.84 + 12 = 30.84 cm.
Marking: 1 m for half circumference, 1 m for total.

Q16. 8 cm
Method: h = V ÷ base area = 200 ÷ 25 = 8 cm.
Marking: 1 m for method, 1 m for answer.

---

Section C (3 marks each)

Q17. 64 cm²
Method: Edge = ∛512 = 8 cm (since 8³ = 512). Face area = 8 × 8 = 64 cm².
Marking: 1 m cube root, 1 m edge, 1 m area.

Q18. 384 cm³
Method: Base area = 8 × 8 = 64 cm². Water height = 6 cm. Volume = 64 × 6 = 384 cm³.
Marking: 1 m base, 1 m multiply, 1 m answer.

Q19. (a) 615.44 cm² (b) 153.86 cm²
Method: (a) A = πr² = 3.14 × 14² = 3.14 × 196 = 615.44 cm².
(b) Quarter = 615.44 ÷ 4 = 153.86 cm².
Marking: 1 m (a), 1 m (b), 1 m units/correct.

Q20. 103.5 cm²
Method: Rectangle area = 12 × 5 = 60 cm². Semicircle area = ½ × πr² = ½ × 3.14 × 5² = ½ × 78.5 = 39.25 cm². Total = 60 + 39.25 = 99.25 cm².
Correction: ½ × 3.14 × 25 = 39.25; total = 99.25 cm² (not 103.5).
Final: 99.25 cm².
Marking: 1 m rectangle, 1 m semicircle, 1 m total.

Note: Q20 uses explicit values; no image needed. If visual required, draw rectangle 12×5 with semicircle radius 5 on 12 cm side.
