Only smarties have the answer!
You can construct a smarties box using the following two tools:
* Construct the base of the prism by using the regular polygon tool (6 vertices) 
* Use the prism 
or extrude to prism 
tool.
To add the 'open/close' functions, simply use the Net 
tool.
Or you can open the applet below in your smartphone or tablet by searching for the following code: ttdbj7vq

Open up the applet and augment against a smarties box. If the height of a smarties box is 114mm, can you estimate the surface area?
You may find the formula below helpful!
For a regular hexagon of length a, the surface area is given by:
Surface area of regular hexagon =
