Three identical inlet pipes were opened at 10:00 AM to fill up an empty container. At 12:30 PM, 2 identical pipes (having different rate from existing pipe’s rate) are also opened. At 1:30 PM, it still required 1 more hour for all these pipes to fill up the remaining 15 m3 of water. If each of the 2 pipes which were added at 12:30 PM can individually fill up the empty container in 40 hours, then the capacity of the container is ____________ m3.
