That's about the size of my house, I have one in each bedroom (4), one in the basement, one in the hallway next to the bedrooms, one in our family room and one in our formal living room. So it really depends on how many bedrooms you have and your local codes, but for me I used 8 to protect my whole house, but by code I could have gotten away with 6 but added a couple extra for extra piece of mind.
