    ya it's correct . as it is written about the (1 0 0) plane which is in 2D. From diagram or just assume for a plane that there is a square and there are four circles on the each corner of square then what's the total contribution of circles to square =1/4 *4 (imagine the 2D only ,don't get confused in 3D cube,as written)

    it should be 1/8 (neither 1/6 nor 1/4)

    then when we talk about 111 plane then we do 1/6 *3. can you please explain why we take 1by6 in that?
