A wedge of cheese is shaped like a triangular prism. How much plastic wrap is needed to cover the wedge of cheese? the demission's of the cheese is 12cm 5cm 9cm 13cm
287 centimeters squared
330 centimeters squared
810 centimeters squared
240 centimeters squared
To calculate the surface area of the cheese wedge, we need to find the area of each of the five faces.
Face 1: 12cm x 5cm = 60cm squared
Face 2: 12cm x 9cm = 108cm squared
Face 3: 5cm x 9cm = 45cm squared
Face 4 (triangle): (1/2) x 9cm x 13cm = 58.5cm squared
Face 5 (triangle): (1/2) x 5cm x 13cm = 32.5cm squared
Total surface area = 60cm squared + 108cm squared + 45cm squared + 58.5cm squared + 32.5cm squared = 304cm squared
Therefore, the correct answer is not listed among the given options.
