Recall that surface area is the total of the areas of each face on a solid figure. Also remember that the definition of a prism is a three–dimensional figure with two parallel congruent polygons as bases, with rectangular side faces. Finally, remember the formula for finding the surface area of a triangular prism is
Toblerone is a brand of chocolate famous for not only its great taste and various flavors (ranging from plain chocolate to honeycomb crisp) but also its distinct triangular packaging. This makes Toblerone chocolate a perfect example of a triangular prism.
1. Do some research on the Toblerone chocolate. What different sizes of chocolate does Toblerone offer?
2. Using the dimensions of a standard Toblerone bar, how much wrapping paper do you need to remove to get to the chocolate? (Hint: Use the resources)
3. How much chocolate is in a Toblerone bar in proportion to its surface area? What does this tell you?
