A square pyramid has one square base and four triangular faces. Let's take a look at the given diagram.
We can use the net of this 3-dimensional shape to find its surface area.
The surface area of a pyramid is the sum of the area of the base and the areas of the lateral faces. Let's calculate the area of the base and the faces one at a time. Then we can add them together.
Looking at the net of this solid, the base is a square with a side length of 6 inches. The square's area is the square of the side length. Therefore, the area of our base is 6^2 = 36 square inches.
Finally, to find the surface area of the square pyramid, we will add the area of the base and the area of the four lateral faces. Surface Area of the Square Pyramid 36+ 96=132square inches Therefore, the correct option is H.
