A certain place suffered from a drought. In order to solve the problem of drinking water for residents, the government built a reservoir next to a mountain spring, and 40 cubic meters of water was injected into the reservoir every hour. When 5 pumps are operated, the pool water will be pumped out in 2.5 hours, and when 8 pumps are operated, the pool water will be pumped out in 1.5 hours. How many cubic meters of water can this reservoir hold?
