You have six faces. Two are bounded by length and width, two by length and depth, and two by width and depth. Each face has an area of the two dimensions that bound it (from the formula for the area of a rectangle).
F1 = L * W
F2 = L * W
F3 = L * D
F4 = L * D
F5 = W * D
F6 = W * D
Adding these six together gives the total surface area, which, simplified, produces:
SAcuboid = 2(LW + LD + WD)

What is the formula for surface area?
2(l*w)+2(l*h)+2(w*h) * * * * * That is only true for a cuboid. Other bodies also have surface areas and there are lots of formulae dealing with them.
How do you minimize the surface area of cuboid?
Make it infinitesimally small.
How do you calculate the surface areas?
The answer will depend on what the surface area is of. The surface areas of regular shapes are can be calculated from formulae but these will depend on the shapes. For non-regular areas there may or may not be simple formulae.

What is total surface area of cuboid 1.45X1.45X5?
Surface area of a cuboid with sides x, y and z is 2(xy+yz+zx) So surface = 2*(1.45*1.45 + 1.45*5 + 5*1.45) = 2*16.6025 = 33.205

What is the derivation of the formulae of the surface area of a cone?
You can approximate the surface area by lots of triangles (base of the triangle on the base of the cone, and tip of the triangle at the tip of the cone), and analyze what happens when the triangles get narrower and narrower.

What is the derivation of the formulae of the surface area of a cube?
Surface Area of a cube is equal to the sum of the area of it sides. Each of its sides are square of side length a. Each side has area of a2. There are 6 sides on a cube. a2 + a2+ a2+ a2+ a2+ a2 = 6a2 Therefore: Surface area of a cube is 6a2
How do you get lateral surface area of cube and cuboid?
Lateral surface area of a cuboid = 2 (Length + Breadth) × Height Lateral surface area of a cube = 4 × Side2
What is the area of a cuboid 4cm by 2cm?
A cuboid is a 3 dimensional object and 3 measures are required for the total surface area of a cuboid.
How do you use the formula for a triangular prism?

Formula of surface area of cuboid?
Let its dimensions be a, b and c:- Surface area of the cuboid: 2*(a*b)+2*(b*c)+2*(a*c) in square units
How can you use the formula for the surface area of a box to find the surface area of a cube?
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.
Can a cuboid with the same value have the same surface area?
yes
How do you minimize the surface area of cuboid?
Make it infinitesimally small.
