Explanation:
The surface area (\(A\)) of a square pyramid is given by the formula:
\[ A = b^2 + 2bh \]
where \(b\) is the base length and \(h\) is the height.
Given a base length \(b = 30\) inches and a height \(h = 26\) inches, substitute these values into the formula:
\[ A = (30)^2 + 2 \times 30 \times 26 \]
Now calculate this expression:
\[ A = 900 + 1,560 \]
\[ A = 2,460 \]
So, the surface area of the square pyramid is \(2,460\) square inches. Therefore, the correct option is O A. \(2,460\) square inches.
