A painter uses 8 liters of paint to cover a large wall section. This amount of paint is enough to cover 48 square meters if applied thinly. However, the painter usually applies thicker coats, for which this same amount of paint is only enough for 32 square meters. If the painter wants to cover a proportionally smaller area using the efficient thin-application rate, specifically enough for just 36 square meters, how many liters of paint should they use?
