For a cuboid, the total surface area = 2*(L*B + B*H + H*L) square units where L = length, B = breadth and H = height.In the case of a cube, L = B = H and so the total surface area is 6*L^2 square units.

Lateral surface area of a cuboid = 2 (Length + Breadth) × Height Lateral surface area of a cube = 4 × Side2
The surface area of a box, which is a cuboid, depends on its length, width and height. A cube is a special type of cuboid in which the length , width and height are all the same.
derivation of surface area of cuboid
Add all the area of six faces of the box in gerneral the surface area of a cube shape box is 6a2 and of cuboid is 2(lb x bh x hl)
A cuboid is a 3 dimensional object and 3 measures are required for the total surface area of a cuboid.
