The surface area of a triangular prism can be calculated by finding the sum of the areas of all the faces.
In this case, the triangular prism has 3 rectangular faces and 2 triangular faces.
The two triangular faces have equal base and height, so the area of one triangle is 1/2 * base * height = 1/2 * 5cm * 4cm = 10 square cm. Since there are 2 of these triangles, the total area for both is 2 * 10 = 20 square cm.
The rectangular faces have dimensions of 5cm by 10cm, which gives an area of 5cm * 10cm = 50 square cm each. Since there are 3 rectangular faces, the total area for all three is 3 * 50 = 150 square cm.
Adding all the areas together, the total surface area of the net of the triangular prism is 20 + 150 = 170 square cm.
Therefore, the surface area of the net of the triangular prism is 170 square centimeters.
