The net below can be folded to form a square pyramid.
topjm [15]

Surface area of the square pyramid = 217.8 in²

Solution:

Side length of the square = 9 in

Area of the square = side × side

                                = 9 in × 9 in

                                = 81 in²

Area of the square = 81 in²

Perimeter of the base = 4 × 9 in = 36 in

Slant height of the triangle = 7.6 in

Surface area of the square pyramid

                            $=\frac{1}{2} \times \text{Perimeter} \times \text{Slant height} + \text{Base area}

                            $=\frac{1}{2}\times  36\times 7.6+81

                            $=136.8+81

                            = 217.8 in²

Surface area of the square pyramid = 217.8 in²
