square centimeters

1 answer

The net of the triangular prism consists of three rectangles and two triangles.

Rectangle 1: 10 cm x 5 cm = 50 cm^2
Rectangle 2: 4 cm x 5 cm = 20 cm^2
Rectangle 3: 5 cm x 5 cm = 25 cm^2

Triangle 1: (1/2) x 5 cm x 4 cm = 10 cm^2
Triangle 2: (1/2) x 5 cm x 4 cm = 10 cm^2

Total surface area = 50 cm^2 + 20 cm^2 + 25 cm^2 + 10 cm^2 + 10 cm^2 = 115 cm^2

Therefore, the surface area of the net of the triangular prism is 115 square centimeters.
