Question

Leon has a piece of cheese shaped like a triangular prism that he needs to wrap in plastic wrap.

Answer 1

The answer is 96 inches squared

Answer 2

Answer:

Option C. 96 in² is the answer.

Step-by-step explanation:

Leon has a piece of cheese, shaped like a triangular prism.

He needs a plastic wrap to cover this prism.

For this we have to calculate the minimum amount of plastic wrap he will require to cover.

Amount of plastic wrap required = Total surface area of the wrap = Surface area of the triangular cheese

Surface area of the wrap = Area of two side triangles + Area of the rectangular sides

= $2(\frac{1}{2})(Base)(Height) + 3(Length)(Width)$

= (Base × Height) + 3(length)(Width)

= (3×4) + 3(7×4)

= 12 + (3×28)

= 12 + 84

= 96 in²

Option C. 96 in² is the correct option.
