The formula for finding the surface area of a triangular prism is:
Surface Area = 2*(base area) + (perimeter of base * height)
In the case of a wedge of cheese, the base is a triangle and the height is the same as the height of the prism.
To find the amount of plastic wrap needed to cover the wedge of cheese, you will first need to calculate the area of the base triangle and the perimeter of the base triangle. Then plug those values into the formula above with the height of the prism.
Once you have calculated the surface area of the wedge of cheese, you will then need to add a little extra to account for overlapping and securing the plastic wrap.
You will use this formula:
Surface Area + (extra amount for overlapping and securing) = Total amount of plastic wrap needed.
Surface Area = 2*(base area) + (perimeter of base * height)
