To find the amount of plastic wrap needed to cover the wedge of cheese, we need to calculate the surface area of the triangular prism.
The formula for finding the surface area of a triangular prism is:
Surface Area = (2 x base area) + (base perimeter x height)
First, we need to find the base area of the triangular prism. The base of the prism is a triangle with base of 12 cm and height of 9 cm. The formula for finding the area of a triangle is:
Area = 1/2 x base x height
Area = 1/2 x 12 x 9
Area = 54 cm^2
Next, we need to find the base perimeter of the prism. Since the base of the prism is a triangle, the base perimeter is the sum of all three sides. The base perimeter is:
12 + 5 + 13 = 30 cm
Now, we can calculate the surface area of the prism:
Surface Area = (2 x 54) + (30 x 9)
Surface Area = 108 + 270
Surface Area = 378 cm^2
Therefore, the amount of plastic wrap needed to cover the wedge of cheese is 378 cm. However, this is not one of the answer options given. It seems there may be a mistake in the answer choices.
Unit six surface area less than five applications of surface area of prisms. Five question quick check question number three use the image to answer the question we have on the first side 12 cm on the left side 5 cm at the top 9 cm on the right side, we have 13 cm in length Where your cheese is shaped like a triangular prism how much plastic wrap is needed to cover the wedge of cheese would it be 287 cm 330 cm 810 cm or 240 cm
