A construction company is building 2 apartment buildings with 12 floors each. The apartments are almost ready to sell but all of them need doors to be completed. Each floor has 6 apartments, and each apartment needs 7 doors in total. How many doors does the company need to buy? Let's think first. Chain of thought:
The number of floors is 12 floors / building x 2 buildings = 24 floors. The number of apartments is 6 apartments / floor x 24 floors = 144 apartments. The company has to buy 7 doors / apartment x 144 apartments = 1008 doors.
Therefore, the answer is 1008.
