1.
3.6 km = 3.6 × 1000 = 3600 m.
Reason: 1 km = 1000 m.
2.
420 cm = 420 ÷ 100 = 4.2 m.
Reason: 1 m = 100 cm.
3.
0.8 m = 0.8 × 1000 = 800 mm.
Reason: 1 m = 1000 mm.
4.
2500 mm = 2500 ÷ 1000 = 2.5 m.
5.
7.25 m = 7.25 × 100 = 725 cm.
6.
32,000 m² ÷ 10,000 = 3.2 hectares.
7.
3.5 m² = 3.5 × (100²) = 3.5 × 10,000 = 35,000 cm².
Reason: 1 m² = 10,000 cm².
8.
0.06 km² = 0.06 × (1000²) = 0.06 × 1,000,000 = 60,000 m².
9.
4 m² = 4 × 10,000 = 40,000 cm².
10.
850,000 cm² ÷ 10,000 = 85 m².
11.
1.25 m³ = 1.25 × (100³) = 1.25 × 1,000,000 = 1,250,000 cm³.
12.
6400 cm³ ÷ 1000 = 6.4 litres.
13.
3.5 m³ = 3.5 × 1000 = 3500 litres.
Reason: 1 m³ = 1000 litres.
14.
45,000 litres = 45,000 ÷ 1000 = 45 m³.
15.
18,500 ml ÷ 1000 = 18.5 litres.
16.
7.2 litres = 7.2 × 1000 = 7200 cm³.
17.
4.5 kg × 1000 = 4500 g.
18.
250 g ÷ 1000 = 0.25 kg.
19.
0.003 tonnes × 1000 = 3 kg.
20.
4.2 kg × 1000 = 4200 g.
21.
Length = 2.4 m, width = 180 cm = 1.8 m.
Area = 2.4 × 1.8 = 4.32 m².
22.
Length = 350 cm = 3.5 m, width = 1.2 m.
Area = 3.5 × 1.2 = 4.2 m².
23.
Dimensions: 1.2 m × 0.8 m × 0.5 m.
Volume = 0.48 m³.
24.
Volume = 25 × 10 × 2 = 500 m³.
Capacity = 500 × 1000 = 500,000 litres.
25.
0.75 m³ = 0.75 × 1000 = 750 litres.
26.
3.6 m³ = 3.6 × 1000 = 3600 litres.
27.
24 litres = 24 × 1000 = 24,000 cm³.
28.
1.2 hectares = 1.2 × 10,000 = 12,000 m².
29.
0.045 km² = 0.045 × 100 = 4.5 hectares.
Reason: 1 km² = 100 hectares.
30.
240 m² = 240 × 10,000 = 2,400,000 cm².
