Read this question in English
Consider the following:
1. 1000 litres = 1 m³
2. 1 metric ton = 1000 kg
3. 1 hectare = 10000 m²
Which of the above are correct?
(a) 1 and 2 only · (b) 2 and 3 only · (c) 1 and 3 only · (d) 1, 2 and 3
उत्तर और व्याख्या · explanation in English
Answer: (d) 1, 2 और 3
All three are standard metric equivalences: a cubic metre holds 1000 litres, a metric ton (tonne) is 1000 kg, and a hectare is a 100 m × 100 m square, i.e. 10000 m².
- 1 m³ = 100 cm × 100 cm × 100 cm = 10,00,000 cm³, and 1 litre = 1000 cm³, so 1 m³ = 1000 litres.
- 1 metric ton (tonne) = 1000 kg by definition.
- 1 hectare = 100 m × 100 m = 10000 m².
- All three statements are correct.
- ✓ 1. 1 m³ = 10,00,000 cm³ and 1 litre = 1000 cm³, so 1 m³ = 1000 litres.
- ✓ 2. A metric ton (tonne) is defined as 1000 kg.
- ✓ 3. A hectare is the area of a square of side 100 m: 100 × 100 = 10000 m².
Remember · Know the core metric links: 1 litre = 1000 cm³, 1 m³ = 1000 litres, 1 hectare = 10000 m², 1 tonne = 1000 kg.
