1. 4000 m
1 km = 1000 m. 4 × 1000 = 4000 m.
2. 700 cm
1 m = 100 cm. 7 × 100 = 700 cm.
3. 8000 mL
1 L = 1000 mL. 8 × 1000 = 8000 mL.
4. 5000 g
1 kg = 1000 g. 5 × 1000 = 5000 g.
5. 1600 m
1 km = 1000 m. 1.6 × 1000 = 1600 m.
6. 520 cm
1 m = 100 cm. 5.2 × 100 = 520 cm.
7. 4800 mL
1 L = 1000 mL. 4.8 × 1000 = 4800 mL.
8. 8800 m
1 km = 1000 m. 8.8 × 1000 = 8800 m.
9. 8100 g
1 kg = 1000 g. 8.1 × 1000 = 8100 g.
10. 300 cm
1 m = 100 cm. 3 × 100 = 300 cm.
11. 320 cm
1 m = 100 cm. 3.2 × 100 = 320 cm.
