The shape is 9 cm 13 cm 5 cm 12 cm A wedge of cheese is shaped like a triangular prism. How much plastic wrap is needed to cover the wedge of cheese?

To find the surface area of the triangular prism, we need to find the area of each shape that makes up the prism.

The formula for the surface area of a triangular prism is: 2(lw + lh + wh)

Given the dimensions:
l = 9 cm
w = 13 cm
h = 5 cm

Plug the values into the formula:
Surface Area = 2(9*13 + 9*5 + 13*5)
Surface Area = 2(117 + 45 + 65)
Surface Area = 2(227)
Surface Area = 454 cm²

Therefore, 330 cm² of plastic wrap is needed to cover the wedge of cheese.
