My cockapoo puppy bites everything?

last week I got a cockapoo (spoodle) puppy. he is 10 weeks old and he bites everything! my hands, feet, the couch, the wood on his kennel and even his bed. he also eats everything. when i take him outside he eats twigs, paper and tries to bite the door. he has 6 toys that he can chew on but he seems more interested in other things. he sleeps in the laundry a night. i give him lots of attention and good food and clean water, i know it is normal for puppy to bite but he does it a lot! what should i do?
