Love helping people so here's the answer :)
Explanation:
A square pyramid has 5 faces: 1 square base and 4 triangular faces. The surface area of the pyramid is the sum of the areas of all its faces.
The area of the square base is 1 * 1 = 1 square inch.
The area of each triangular face is (1/2) * base * height = (1/2) * 1 * 2 = 1 square inch.
Since there are 4 triangular faces, the total area of the triangular faces is 4 * 1 = 4 square inches.
Therefore, the surface area of the pyramid is 1 + 4 = 5 square inches.
