Answer:
To find the surface area of the triangular prism, you need to add all the outer faces of the prism. Talking about the outer faces, there are three rectangles and two right triangles. By summing up the area of these shapes, the surface area of the prism can be calculated.
Area of the three rectangles = 8x5 + 6x5 + 10x5 = 40 + 30 + 50 = 120 sq. inches
Area of two right triangles = (1/2) x 8 x 6 + (1/2) x8x6 = 48 sq.inches
So, surface area of triangular prism = Area of three rectangles + Area of two right triangles
or, Surface area = 120 + 48 = 168 sq.inches
