Ok thanks. Now I know what you guys were talking about. I though he meant a point INSIDE the box say (h,j,k). I think that's a little more difficult: what is the volume of the solid formed by all points inside the box that are a distance of 1 unit away from the point (say for a box 2x2x2)? Are there points in the box that yield a miniumum volume? Is it at the corners? So conceivably, we could construct a function of 3 variables: f(x,y,z), which yields this volume as a function of position in the box. Really, I think just calculating one such volume would be difficult.
can someone please explain where the l(pi)+h(pi)+w(pi) came from. sorry im a physics student and we were given a similar problem, and i just dont really understand. our was for a different shape and different distance but i think this helps.
