Answer:
lateral surface area of the triangular prism = 128 cm²
Explanation:
The question is incomplete the picture below represents the complete question.
Lateral surface area of a triangular prism = PH
where
p = perimeter of the triangle
H = height of the prism
perimeter = 5 + 5 + 6 = 16 cm
height of the prism = 8 cm
Lateral surface area of a triangular prism = Perimeter of the triangle × height of the prism
lateral surface area of the triangular prism = 16 × 8
lateral surface area of the triangular prism = 128 cm²
