Find the volume of the largest rectangular box with edges parallel to the axes that can be inscribed in the ellipsoid 7² 2 y² + 81 25 + 64 =1 Hint: By symmetry, you can restrict your attention to the first octant (where z, y, z 20), and assume your volume has the form V = 8zyz. Then arguing by symmetry, you need only look for points which achieve the maximum which lie in the first octant. Maximum volume:
