The total area of cardboard needed is equal to 121.34 square centimeters.

<h3>How many square centimeters area needed for the box?</h3>

This is equal to the surface of the given chocolate.

First, we will have two sides that are rectangles measuring 16cm by 2.6cm, so the area is:

A = 16cm*2.6cm = 41.6cm^2

Then we have another rectangular side which is the bottom one, that is a rectangle of 2.2cm by 16cm, so the are is:

A' = 2.2cm*16cm = 35.2cm^2

Finally, we have the areas of the two triangular faces, the areas of these are:

A'' = 2.2cm*3cm/2 = 1.47cm^2

Then the total area of cardboard needed is:

area = 2*A + A' + 2*A'' = 2*41.6cm^2 + 35.2cm^2 + 2* 1.47cm^2 = 121.34 cm^2
