What will be an ideal response?


The sphere centered at (x0, y0, z0) of radius ? circumscribes the cube centered at  and with sides  Therefore,   and  imply  Likewise, the cube centered at  with sides 2? circumscribes the sphere with radius ?. Thus,  implies   and  The requirements are equivalent.
