Read this question in English
If 1 litre of water weighs 1 kg, then how many cubic millimetres of water will weigh 0.1 gm?
(a) 1 · (b) 10 · (c) 100 · (d) 1000
उत्तर और व्याख्या · explanation in English
Answer: (c) 100
1 litre = 1 kg means 1 gram of water occupies 1 cm³. Since 1 cm³ = 10 × 10 × 10 = 1000 mm³, 0·1 g occupies 100 mm³.
- 1 litre = 1000 cm³ weighs 1 kg = 1000 g, so 1 g of water = 1 cm³.
- 1 cm³ = 10 mm × 10 mm × 10 mm = 1000 mm³.
- 0·1 g = 0·1 cm³ = 100 mm³.
Remember · Water: 1 g = 1 cm³ = 1 mL; and 1 cm³ = 1000 mm³.
