Millilitres and cubic centimetres worksheet: Answers and working

1. 25
How many mL does a space of 1 cm³ hold? Think whether the number changes.
A space of 1 cm³ holds exactly 1 mL: the number stays the same, 25 mL.
2. 3000
1 L = 1000 mL = 1000 cm³, so 3 L is 3 lots of 1000.
1 L = 1000 mL = 1000 cm³: 3 × 1000 = 3000.
3. 6000
1 L = 1000 mL = 1000 cm³, so 6 L is 6 lots of 1000.
1 L = 1000 mL = 1000 cm³: 6 × 1000 = 6000.
4. 85
How many mL does a space of 1 cm³ hold? Think whether the number changes.
A space of 1 cm³ holds exactly 1 mL: the number stays the same, 85 mL.
5. 385 mL
Find the inside volume first: length × width × height. 1 cm³ holds 1 mL.
The inside is 7 × 5 × 11 = 385 cm³, and 1 cm³ holds 1 mL: 385 mL.
6. 3.7
3700 cm³ is 3700 mL. 1000 mL make 1 L, so divide by 1000.
3700 cm³ = 3700 mL; 1000 mL is 1 L, so 3700 ÷ 1000 = 3.7.
7. 240 mL
Find the inside volume first: length × width × height. 1 cm³ holds 1 mL.
The inside is 3 × 10 × 8 = 240 cm³, and 1 cm³ holds 1 mL: 240 mL.
8. 4.4
4400 cm³ is 4400 mL. 1000 mL make 1 L, so divide by 1000.
4400 cm³ = 4400 mL; 1000 mL is 1 L, so 4400 ÷ 1000 = 4.4.
9. 12 L
Find the tank's inside volume first, 60 × 10 × 20 cm³, then change it into litres.
60 × 10 × 20 = 12000 cm³ = 12000 mL; 12000 ÷ 1000 = 12 L.

10. C. 280 cm³
How much space does 1 mL take up? Remember 1 mL = 1 cm³, and check the unit is a volume.
1 mL = 1 cm³, so 280 mL of water takes up 280 cm³.
11. True
1 L = 1000 cm³. Change 3 L into cm³, add 200, and compare with 3200.
1 L = 1000 cm³ and 1 mL = 1 cm³: 3 × 1000 + 200 = 3200.
12. False
1 L = 1000 cm³. Change 2 L into cm³, add 600, and compare with 800.
1 L = 1000 cm³ and 1 mL = 1 cm³: 2 × 1000 + 600 = 2600.

Marking: 2 for the working, 1 for the answer, 1 for the sentence.

13. 4800 L
The units must match: change 4 m and 3 m into centimetres first, then find the water's volume.
All in centimetres first: 4 m = 400 cm, 3 m = 300 cm; 400 × 300 × 40 = 4800000 cm³, and 4800000 ÷ 1000 = 4800 L.
14. 192 mL
Find the inside volume first: 4 × 6 × 8 cm³. 1 cm³ holds 1 mL.
4 × 6 × 8 = 192 cm³, which is 192 mL.
15. 9 times
15 cm³ is 15 mL. See how many lots of 15 mL there are in 135 mL.
15 cm³ is 15 mL: 135 ÷ 15 = 9 times.
16. 32 boxes
First find how many mL one box holds, 5 × 5 × 5, and change 4 L into mL.
Each box is 5 × 5 × 5 = 125 cm³, 125 mL; 4 L = 4000 mL, and 4000 ÷ 125 = 32 boxes.
17. 72 mL
Find one cup's volume first, 2 × 2 × 2 cm³, then think about all 9.
Each cup is 2 × 2 × 2 = 8 cm³ = 8 mL; 8 × 9 = 72 mL.
18. 13 times
10 cm³ is 10 mL. See how many lots of 10 mL there are in 130 mL.
10 cm³ is 10 mL: 130 ÷ 10 = 13 times.
