Answer:
Thea answer is below
Explanation:
A triangular prism is a polyhedron (a three dimensional shape) made of a triangular base and 3 faces joining corresponding sides.
The triangular prim has 5 faces of which two are triangular and three are rectangular. It also has 6 vertices and 9 edges.
The lateral surface area of a triangular prism = (a + b + c)h; where a, b and c are the sides of the triangular base and h is the height of the triangle.
Given that a = b = c = 6 cm, h = 15 cm. Hence:
Lateral surface area = (6 + 6 + 6)15 = 270 cm²
