Total surface area of cuboid

In Geometry, a cuboid is defined as a convex polyhedron bounded by 6 quadrilateral faces given that its polyhedral graphs is same as that of a cube. The total surface area (TSA) of a cuboid is the sum of the areas of its six faces.

Some sources also define cuboid as a polyhedron whose 6 faces are rectangular, in which case it is also called a right cuboid or a rectangular box. A cuboid has 6 faces, 8 vertices and 12 edges.
