The surface area of a triangular prism can be calculated by finding the area of all its faces and summing them up.
Assuming the triangular bases have sides measuring 6 cm, 8 cm, and 10 cm each:
Area of both triangular bases = (1/2) * base * height = (1/2) * 6 * 8 = 24 square centimeters per base. Since there are two bases, the total area for both bases is 48 square centimeters.
Area of each rectangular face = width * height = 10 * 6 = 60 square centimeters per face. Since there are three rectangular faces, the total area is 180 square centimeters.
Therefore, the total surface area of the triangular prism is 48 + 180 = 228 square centimeters.
None of the given options match precisely, so a close approximation would be 20 square centimeters.
