2. Explanation - 2.73 kg is 2730 grams so since it says that after two months meaning its the total grams and 2730g + 1500g is 4,230 and if you convert you need to multiply 4,230 grams and the formula to convert is to multiply by 1000.

3. Explanation - 12 cubic meters in liters is 12,000 and formula of it to convert cubic meters is to multiply the volume by 1000 and 12 x 1000 is 12,000
