Answer»

The correct answer is (d) Rectangular

To elaborate: In geometry, a cuboid is a convex POLYHEDRON bounded by six quadrilateral FACES, whose polyhedral graph is the same as that of a cube. While mathematical literature refers to any such polyhedron as a cuboid, other sources use “cuboid” to refer to a shape of this TYPE in which each of the faces is a rectangle (and so each pair of adjacent faces meets in a right angle); this more restrictive type of cuboid is ALSO known as a rectangular cuboid, right cuboid, rectangular box, rectangular hexahedron, right rectangular PRISM, or rectangular parallelepiped.
