Problem:
A plastic container holds 10 liters of kerosene. One liter of kerosene weighs 0.8kg, and an empty container weighs 1.3kg. How much does the container of kerosene weigh in kilograms?
Solution Method:
* Problem Summary:
1 plastic container: 10 liters of kerosene
Weight of 1 liter of kerosene: 0.8 kg
Weight of empty container: 1.3 kg
Total weight of the kerosene container: ? kg
* Problem-solving approach:
- Find the weight of 10 liters of kerosene by multiplying the number of liters of kerosene in the container by the weight of 1 liter of kerosene
- Find the total weight of the kerosene container by adding the weight of 10 liters of kerosene (previously found) to the weight of the empty container.
Answer:
10 liters of kerosene weigh:
0.8 x 10 = 8(kg)
The total weight of the kerosene container is:
8 + 1.3 = 9.3(kg)
Final Answer: 9.3 kg.
