Question

The chocolate candy below is being wrapped in a cardboard box. How many square centimeters area needed for the box?

Answer 1

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

How many square centimeters area needed for the box?

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:

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