A triangular prism has a base with a height of 5 cm and a base length of 6 cm. If the prism is 10 cm long, what is its surface area?

15 + 30 + 25 + (√80 * 10) cm²

30 + 60 + 50 + (√61 * 10) cm²

20 + 40 + 30 + (√50 * 10) cm²

25 + 50 + 45 + (√70 * 10) cm²

MULTIPLE CHOICE QUESTION

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
