The sum of lengths of all edges of a rectangular box is  140 cm and the distance from one corner
of the box to the farthest corner is 21 cm.  What is the total surface area of the box?

In rectangular Angles, and opposite faces of a cuboid are equal. The square cuboid, square box, or right square prism (also ambiguously called square prism) is a special case of the cuboid in which at least two faces are squares.

All angles are right angles, and opposite faces of a cuboid are equal.
