He cut a round door out of the front the area of the door is 5.7 square inches what is the area of the rest of the birdhouse? Perito Apr 17, 2009, 05:04 AM Are we talking about the surface area of the birdhouse? It seems so. The front is 4 x 7. The door is 5.7 square inches. We need to know the shape of the birdhouse. Is it a cube? Does it have a pitched roof like many houses? If it's a cube, then there are 6 sides and each side is 4 x 7 (4)(7)(6)=168\,in^2 However, we have a 5.7 square inch hole that we have to subtract from the area: 168\,in^2\,-5.7\,=\,162.3\,in^2 Copyright ©2005-, Ask Me Help Desk
