Grade 3 Maths Worksheets: (13.5 Measurement of Capacity ... - Free Printable

Sure! Let’s solve each multiplication problem on the worksheet “Multiplication of Litres and Millilitres – Worksheet #9”. The problems involve multiplying volumes (in litres or millilitres) by whole numbers. We’ll calculate each one step-by-step and provide the answer with the correct unit.

✔ Key Notes:

- Litres (L) and millilitres (mL) are units of volume.
- 1 L = 1000 mL, but since we’re only multiplying, we don’t need to convert unless asked — we just multiply the number and keep the same unit.
- All answers will be in the same unit as the original (L or mL).

## 🔢 Solutions:

1. 54 L × 8 =

→ 54 × 8 = 432 → 432 L

2. 250 mL × 4 =

→ 250 × 4 = 1000 → 1000 mL

3. 830 mL × 5 =

→ 830 × 5 = 4150 → 4150 mL

4. 76 L × 11 =

→ 76 × 11 = 76 × (10 + 1) = 760 + 76 = 836 → 836 L

5. 33 L × 8 =

→ 33 × 8 = 264 → 264 L

6. 905 mL × 3 =

→ 905 × 3 = (900 × 3) + (5 × 3) = 2700 + 15 = 2715 → 2715 mL

7. 291 L × 6 =

→ 291 × 6 = (300 - 9) × 6 = 1800 - 54 = 1746 → 1746 L

8. 565 mL × 9 =

→ 565 × 9 = (500 × 9) + (60 × 9) + (5 × 9) = 4500 + 540 + 45 = 5085 → 5085 mL

9. 325 mL × 3 =

→ 325 × 3 = (300 × 3) + (25 × 3) = 900 + 75 = 975 → 975 mL

10. 74 L × 10 =

→ 74 × 10 = 740 → 740 L

11. 29 L × 18 =

→ 29 × 18 = 29 × (20 - 2) = 580 - 58 = 522 → 522 L

12. 400 mL × 8 =

→ 400 × 8 = 3200 → 3200 mL

13. 925 mL × 5 =

→ 925 × 5 = (900 × 5) + (25 × 5) = 4500 + 125 = 4625 → 4625 mL

14. 18 L × 20 =

→ 18 × 20 = 360 → 360 L

15. 39 L × 19 =

→ 39 × 19 = 39 × (20 - 1) = 780 - 39 = 741 → 741 L

16. 47 mL × 8 =

→ 47 × 8 = (40 × 8) + (7 × 8) = 320 + 56 = 376 → 376 mL

17. 50 L × 7 =

→ 50 × 7 = 350 → 350 L

18. 825 mL × 2 =

→ 825 × 2 = 1650 → 1650 mL
