Chocolate Bliss Candy Company makes a candy bar in the shape of a triangular prism. This diagram shows the
net of the prism. For packaging, each triangular base is covered in gold foil. Each rectangular face is covered in
red foil. How many square centimeters of red foil are used for each candy bar?

Answer 1

I’m missing how the numbers line up on the net. To find the red foil area you need the three side lengths of the triangular base (call their sum P) and the prism length (call it L). The total red foil area = P × L (three rectangles, each side of the triangle × the prism length).

If the triangle sides are 6 cm, 16 cm, and 20 cm and the prism length is 10 cm, then P = 6+16+20 = 42 cm and the red area = 42×10 = 420 cm² — which is not one of the choices you listed.

Could you confirm which three numbers are the triangle’s side lengths and which number is the prism length (or upload the net diagram)? Once I have that I’ll compute which choice is correct.
