Answer 2

Calculation

To calculate the amount of coal needed to replace 30 million cubic meters of gas, we can use the given conversion rate of 5 cubic meters of gas being replaced by 6 kilograms of coal.

First, let's convert 30 million cubic meters of gas to kilograms using the conversion rate:

30 million cubic meters of gas * (6 kilograms of coal / 5 cubic meters of gas) = 36 million kilograms of coal.

Now, let's convert kilograms to tons:

36 million kilograms of coal * (1 ton / 1000 kilograms) = 36,000 tons of coal.

Therefore, to replace 30 million cubic meters of gas, approximately 36,000 tons of coal would be needed.

Please note that the conversion rate provided assumes a specific energy content for both gas and coal, and the actual energy content may vary depending on the specific type and quality of the fuel.

Answer

To replace 30 million cubic meters of gas, approximately 36,000 tons of coal would be needed.
