To determine how many liters of paint are required to cover 400 square meters, we can first find the coverage rate of the paint.
From the information provided:
- 5 liters of paint covers 20 square meters.
To find the coverage per square meter, we can calculate:
\[ \text{Coverage per square meter} = \frac{5 \text{ liters}}{20 \text{ square meters}} = 0.25 \text{ liters/square meter} \]
Now, to find out how many liters are needed to cover 400 square meters, we can multiply the coverage per square meter by the total area:
\[ \text{Liters needed} = 0.25 \text{ liters/square meter} \times 400 \text{ square meters} = 100 \text{ liters} \]
Therefore, 100 liters of paint are required to cover 400 square meters.
