Chocolate bliss makes a candy bar in a shape of a triangular prism. The prism is represent Tidd by the net given for pack, aging. The top and bottom are covered in gold foil, and the faces are covered in red foil. How many centimeters of red foil are needed for one candy bar.

Answer 1

To calculate the amount of red foil needed for one candy bar, we first need to find the surface area of the triangular prism.

The formula for the surface area of a triangular prism is:
Surface Area = 2(base area) + (perimeter of base) * height

Given that the base of the prism is a triangle, we need to calculate the area of the base triangle first. Let's assume the dimensions of the base triangle are:
- Base: 5 cm
- Height: 4 cm

Base area = 1/2 * base * height
Base area = 1/2 * 5 * 4
Base area = 10 cm^2

Now, let's calculate the perimeter of the base triangle:
Perimeter = sum of all three sides
Perimeter = 5 + 5 + 5
Perimeter = 15 cm

Now, we can calculate the total surface area of the triangular prism:
Surface Area = 2(10) + (15 * 4)
Surface Area = 20 + 60
Surface Area = 80 cm^2

Since both faces of the prism are covered in red foil, the total amount of red foil needed for one candy bar is equal to the surface area of the prism:
80 cm^2

Therefore, 80 square centimeters of red foil are needed for one candy bar.
