A triangular prism has base side lengths 5 cm, 6 cm, and 7 cm and height 10 cm. What is its lateral surface area?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 180 cm2
Lateral surface area of a triangular prism = Perimeter of base × Height of prism
Perimeter of triangular base = 5 + 6 + 7 = 18 cm
Lateral surface area = 18 × 10 = 180 cm2
Therefore, the lateral surface area is 180 cm2.
