Answer:
The correct answer is first option. 204 m²
Explanation:
Formula:-
Lateral surface area of square pyramid = 4 * area of triangle
To find the slant height of triangle(l)
l = √(6² + 6²) = 6√2
To find the area of triangle
Area = bh/2
b = 12 m
h = 6√2
Area = (12 * 6√2)/2 = 36√2
To find the lateral surface area of Prism
Lateral surface area of square pyramid = 4 * area of triangle
= 36√2 * 4 = 203.64 ≈ 204 m²
First answer is the correct option
