Answer 2

The answer should be 4. Because in each cube you take from one corner,it seems like you lost 3 square shaped area but when you remove the cube, there occurs the hidden 3 square shaped area under that cube. So the surface area doesn't change. You should try to imagine the cube, it may help.
