The base of a right prism is a right-angled triangle whose two shorter sides are 6 cm and 8 cm, and the prism is 12 cm long. Find its total surface area in cm².

Question

Accepted Answer

336. The hypotenuse = √(36 + 64) = 10 cm, so the base perimeter = 6 + 8 + 10 = 24 cm and the base area = ½ × 6 × 8 = 24 cm². Lateral surface = perimeter × length = 24 × 12 = 288 cm², and the two triangular ends add 2 × 24 = 48 cm². Total = 288 + 48 = 336 cm².
