A Mighty Big Birdhouse

This is a condominium for birds called Purple Martins. It was built by Amish carpenters out of recycled lumber and roofing and sold for $80 at Todd's Farm. Okay, let's do a little math. Can you figure out how many doors there are going into the whole house? Think "Multiplication". (All the sides are the same.)
