A triangular prism has a base area of 24 cm² and a height of 8 cm. What is the total surface area of the prism if the lateral faces are rectangles?
Total surface area = 2 * Base area + 8 = 56 cm²
Total surface area = Lateral surface area + 2 * Base area = P * 8 + 2 * 24 = P * 8 + 48 cm² (where P is the perimeter of the triangular base)
Total surface area = 3 * Base area + Lateral surface area = 72 cm²
Total surface area = P * 10 + 48 cm²
