Apply the technique of using nets to find the surface d arranged this triangular prism your answer should have two decimal places
7.48 cm
13 cm
15 cm
17 cm
To find the surface area of the triangular prism, we need to find the area of each face and then sum them up.
1. Top and Bottom Triangular Faces:
The base of the triangle is 13 cm and the height is 7.48 cm.
Area = 1/2 * base * height = 1/2 * 13 * 7.48 = 48.58 cm² (for each face)
2. Side Rectangular Faces:
The base of the rectangle is 15 cm and the height is 7.48 cm.
Area = base * height = 15 * 7.48 = 112.2 cm² (for each face)
Now, we add up the areas of all the faces:
2 (top and bottom triangular faces) + 3 (side rectangular faces) = 2(48.58) + 3(112.2) = 97.16 + 336.6 = 433.76 cm²
Therefore, the surface area of the triangular prism is 433.76 cm².
