In a wildlife reserve, there are three types of animals: zebras, giraffes, and lions. There are 15 zebras, 10 giraffes, and twice as many lions as there are giraffes. If each zebra weighs 200 kg, each giraffe weighs 800 kg, and each lion weighs 250 kg, calculate the total weight of all the animals in the reserve. Let's think step by step and output the final answer within \boxed{}.
