Six dogs each had 6 puppies. All the dogs and puppies each had 6 fleas. How many legs are there?

Dogs: 6

Puppies: 6*6 = 36

Total legs on dogs and puppies: (6+ 36)*4 = 168

All the dogs and puppies each has 6 fleas and each flea has 6 legs.

Total legs on fleas: (6+36)*6*6 = 1512

Total legs: 168+1512 = 1680.
