Answer:
270 cm²
Explanation:
The question is not complete, but a similar question is attached.
Solution:
A prism is a three dimensional polygon with two identical and opposite faces. These bases are called the base of the polygon.
A triangular prism is a prism in which its bases are triangular in shape and it also has three rectangular sides.
The total surface area (TSA) of a triangular prism is given by:
TSA = area of triangle 1 + area of triangle 2 + area of rectangle 1 + area of rectangle 2 + area of rectangle 3
Area of triangle 1 = (1/2) * base * height = 1/2 * 6 * 5 = 15 cm²
Area of triangle 2 = (1/2) * base * height = 1/2 * 6 * 5 = 15 cm²
Area of rectangle 1 = length * breadth =15 * 6 = 90 cm²
Area of rectangle 2 = length * breadth =15 * 5 = 75 cm²
Area of rectangle 3 = length * breadth =15 * 5 = 75 cm²
TSA = 15 cm² + 15 cm² + 90 cm² + 75 cm² + 75 cm² = 270 cm²
