Answer:
SA = 52900 + 2300√1313 m²
Step-by-step explanation:
The equation of the surface area of a pyramid:
SA = area of base + 0.5 * perimeter of base * slant height
1. Area of the base: Since it's a square base, 230² m² = <em>52900 m²</em>
2. Perimeter of the base: The base is square, 230*4 m = <em>920 m</em>
3. Slant height: 115² + 140² = h² --> h² = 32825 --> h = <em>5√1313 m</em>
Plug in: SA = 52900 + 0.5 * 920 * 5√1313
Multiply: SA = 52900 + 2300√1313 m²
