The surface area of a square pyramid formula is given by:

Surface Area = Base Area + (1/2) * Perimeter of Base * Slant Height

Given that the base edge length is 5 yards and the height is 25 yards, we can calculate the slant height using the Pythagorean theorem:

Slant Height = √(base edge length/2)^2 + height^2
= √(5/2)^2 + 25^2
= √(25/4) + 625
= √(625/4 + 625)
= √(625 + 2500)
= √3125
= 55.90 (rounded to two decimal places)

Now, we can substitute the values into the surface area formula:

Surface Area = (5^2) + (1/2) * 4 * 5 * 55.90
= 25 + 2 * 5 * 55.90
= 25 + 559
= 584

Rounding to the nearest whole number, the surface area of the square pyramid is 584 square yards.

Therefore, none of the provided answer choices are correct.
