2. 7 girls x 2 legs per girl = 14 legs.

7 girls x 7 backpacks = 49 backbacks.

49 backpacks x 7 big dogs = 343 big dogs

343 big dogs x 4 legs per dog = 1372 legs

343 big dogs x 7 puppies = 2401 pupies

2401 puppies x 4 legs per puppy = 9604 legs

Total legs = 9604 + 1372 + 14

Total legs = 10,990 legs

Done!
