It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
You will have to work the surface area of one of the ends and then multiply that with the length.
Form a net of the Toblerone and work out the area of each individual part of it and then add up the parts together to find its entire surface area
work it out
Work out the area of each of the 5 nets and then add them together
To calculate the surface area of a rectangular shape, you need to know the length and width of the rectangle. The formula for the surface area is given by multiplying the length by the width (Surface Area = Length × Width). If you're calculating the surface area of a rectangular prism, you would sum the areas of all six faces, which can be calculated using the formula: Surface Area = 2(length × width + length × height + width × height).
A quadrilateral does not have a surface area because it is not a voluminous figure.
Work out the surface area of its 6 faces individually and then add them together
Total surface area = (2*pi*radius2)+(pi*diameter*height)
You will have to work the surface area of one of the ends and then multiply that with the length.

Another dimension is needed to work out the surface area of the roof.
Work out the area of each of the 5 nets and then add them together
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
Two hemispherical ends = 4*pi*radius2 Lateral surface area of the cylinder = 2*pi*r*lenght of cylinder Work both out separately and the sum of them will give you the total surface area in square units.
The total surface area! The total surface area! The total surface area! The total surface area!
