Find the surface area of a pyramid, explain in detail.

Square bass of 230 meters by 230 meters; height of 140 meters

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 = 52900 m²

2. Perimeter of the base: The base is square, 230*4 m = 920 m

3. Slant height: 115² + 140² = h² - -> h² = 32825 - -> h = 5√1313 m

Plug in: SA = 52900 + 0.5 * 920 * 5√1313

Multiply: SA = 52900 + 2300√1313 m²
