Answer:

  1,493,582.81 ft²

Step-by-step explanation:

The area of one triangular face is found using the formula for the area of a triangle:

  A = 1/2bh

  A = 1/2(755.9 ft)(610 ft) = 230,549.5 ft²

The base area is the area of a square 755.9 ft on a side:

  A = s²

  A = (755.9 ft)² = 571,384.81 ft²

Then the total surface area of the pyramid is the sum of the the areas of four (4) triangular faces and the area of the base.

  SA = 4(230,549.5 ft²) +571,384.81 ft²

  SA = 1,493,582.81 ft²
