Primary 5 Mathematics Quiz - Measurement (Answer Key)

Total Marks: 50

---

Section A: Multiple Choice Questions (10 marks)

1. (2) 3045 m
Working: 3 km = 3000 m, 3000 m + 45 m = 3045 m
Concept: Converting km to m (1 km = 1000 m) and adding.

2. (1) 18 000 cm³
Working: Volume = length × breadth × height of water = 40 × 25 × 18 = 18 000 cm³
Concept: Volume of water in a rectangular tank = base area × water height. Unit is cm³.

3. (2) 7025 g
Working: 7.025 kg = 7 kg + 0.025 kg = 7000 g + 25 g = 7025 g
Concept: 1 kg = 1000 g. Multiply the whole number part by 1000, and the decimal part by 1000.

4. (3) 216 cm³
Working: Volume of cube = side × side × side = 6 × 6 × 6 = 216 cm³
Concept: Volume of cube = side³.

5. (1) 1.15 ℓ
Working: 1.5 ℓ = 1500 mℓ. 1500 mℓ - 350 mℓ = 1150 mℓ = 1.15 ℓ
Concept: Convert to same unit before subtracting. 1 ℓ = 1000 mℓ.

6. (2) 3 kg
Concept: Estimation of mass. A school bag with books is typically 2–5 kg. 300 g is too light (like a phone), 30 kg is too heavy (like a large dog).

7. (1) 1800 cm³
Working: Volume = base area × height = 120 × 15 = 1800 cm³
Concept: Volume = base area × height. Unit is cm³.

8. (1) 5 ℓ 50 mℓ
Working: 5050 mℓ = 5000 mℓ + 50 mℓ = 5 ℓ 50 mℓ
Concept: 1 ℓ = 1000 mℓ. Divide by 1000: quotient is litres, remainder is millilitres.

9. (1) 80 cm
Working: 2 m 40 cm = 240 cm. 240 cm ÷ 3 = 80 cm
Concept: Convert to same unit (cm) before dividing.

10. (1) 4 cm
Working: Volume = length × breadth × height. 240 = 10 × 6 × height. Height = 240 ÷ 60 = 4 cm
Concept: Finding a missing dimension given volume and the other two dimensions.

---

Section B: Short Answer Questions (20 marks)

11. 4085 m
Working: 4 km = 4000 m. 4000 m + 85 m = 4085 m.
Marks: 1 mark for correct conversion of km to m, 1 mark for correct addition and final answer.

12. 60 ℓ
Working: Volume = 50 × 30 × 40 = 60 000 cm³. 60 000 cm³ = 60 ℓ (since 1 ℓ = 1000 cm³).
Marks: 1 mark for correct volume in cm³, 1 mark for correct conversion to litres and final answer.
Common mistake: Forgetting to convert cm³ to ℓ, or dividing by 100 instead of 1000.

13. 1 kg 150 g
Working: 2.5 kg = 2 kg 500 g. 2 kg 500 g - 1 kg 350 g = 1 kg 150 g.
Marks: 1 mark for converting 2.5 kg to 2 kg 500 g (or working in grams), 1 mark for correct subtraction and final answer in kg and g.

14. 768 cm³
Working: Base area = 8 × 8 = 64 cm². Volume = base area × height = 64 × 12 = 768 cm³.
Marks: 1 mark for correct base area, 1 mark for correct volume calculation and unit.
Note: The diagram shows a cuboid with square base of side 8 cm and height 12 cm.

15. 0.4 (or 2/5)
Working: 3.2 ℓ ÷ 8 ℓ = 0.4 pails.
Marks: 1 mark for correct division, 1 mark for correct answer.
Note: The question asks "how many such pails are needed to fill a tank with capacity 3.2 ℓ". Since the pail is larger than the tank, less than 1 pail is needed. Accept 0.4 or 2/5. If the question intended the tank to be larger, the numbers would be swapped. As written, answer is 0.4.

Section C: Structured / Long Answer Questions (20 marks)

16. (a) 72 000 cm³
(b) 48 ℓ

Working for (a):
Volume of tank = 60 × 40 × 50 = 120 000 cm³
Volume of water = $\frac{3}{5}$ × 120 000 = 72 000 cm³

Working for (b):
Volume needed to fill = $\frac{2}{5}$ × 120 000 = 48 000 cm³ = 48 ℓ
(Or: Total capacity = 120 ℓ. Water = 72 ℓ. Needed = 120 - 72 = 48 ℓ)

Marks:

• (a) 2 marks: 1 mark for total volume, 1 mark for fraction calculation and answer.
• (b) 2 marks: 1 mark for finding remaining fraction or subtracting, 1 mark for conversion to ℓ and answer.
  Common mistake: Forgetting to convert cm³ to ℓ in (b), or using wrong fraction.

17. 18.375 ℓ

Working:
Volume of cuboid = 30 × 20 × 25 = 15 000 cm³
Volume of cube = 15 × 15 × 15 = 3375 cm³
Total volume = 15 000 + 3375 = 18 375 cm³ = 18.375 ℓ

Marks:

• 1 mark for volume of cuboid
• 1 mark for volume of cube
• 1 mark for adding volumes
• 1 mark for conversion to ℓ and final answer
  Note: The diagram shows a composite solid. Students must identify the two shapes and their dimensions.

18. (a) 400 mℓ
(b) 800 mℓ

Working:
Total syrup = 2.4 ℓ = 2400 mℓ
Poured into jugs = $\frac{2}{3}$ × 2400 = 1600 mℓ
Each jug = 1600 ÷ 4 = 400 mℓ
Remaining for cup = 2400 - 1600 = 800 mℓ
(Or: $\frac{1}{3}$ × 2400 = 800 mℓ)

Marks:

• (a) 2 marks: 1 mark for finding total poured into jugs (or fraction), 1 mark for dividing by 4 and answer in mℓ.
• (b) 2 marks: 1 mark for finding remaining fraction or subtracting, 1 mark for answer in mℓ.
  Common mistake: Not converting ℓ to mℓ first, or dividing 2.4 by 3 incorrectly.

19. (a) 6 kg 900 g
(b) 5 kg 450 g

Working:
Mass of durian = 2 kg 300 g = 2300 g
(a) Mass of watermelon = 3 × 2300 g = 6900 g = 6 kg 900 g
(b) Mass of pumpkin = 6900 g - 1450 g = 5450 g = 5 kg 450 g

Marks:

• (a) 2 marks: 1 mark for multiplication (×3), 1 mark for conversion to kg and g.
• (b) 2 marks: 1 mark for subtraction of 1 kg 450 g, 1 mark for conversion to kg and g.
  Common mistake: Subtracting 1 kg 450 g from the durian's mass instead of the watermelon's, or incorrect conversion between kg/g.

20. (a) 14 400 cm³
(b) 150

Working:
(a) Volume of water at first = base area × height = 800 × 18 = 14 400 cm³
(b) Height of tank = 30 cm. Rise in water level = 30 - 18 = 12 cm.
Volume displaced by cubes = base area × rise = 800 × 12 = 9600 cm³
Volume of one cube = 4 × 4 × 4 = 64 cm³
Number of cubes = 9600 ÷ 64 = 150

Marks:

• (a) 2 marks: 1 mark for correct formula (base area × height), 1 mark for correct calculation and unit.
• (b) 3 marks: 1 mark for finding rise in water level (12 cm), 1 mark for volume displaced (9600 cm³), 1 mark for volume of one cube and division to get 150.
  (If 4 marks allocated: 1 mark for rise, 1 for displaced volume, 1 for cube volume, 1 for final answer)
  Concept: Displacement method – the volume of water displaced equals the volume of the cubes added. The rise in water level × base area gives the total volume of cubes.
