Base area = 12 x 12 = 144
Next, we have to find the area of each of the 4 triangular faces of the pyramid. The formula to find the area of a triangle is (base x height) / 2. Since the base of each triangle is a side of the square base, we can use the base length of 12.
Triangle area = (12 x 18) / 2 = 216
Since there are 4 triangular faces on the pyramid, we need to find the total area of all 4 together.
Total triangular area = 216 x 4 = 864
then add the base area and the total triangular area together to find the total surface area of the square pyramid.
Total surface area = Base area + Total triangular area = 144 + 864 = 1008
The surface area of the square pyramid is 1008 square units.

So, to find the surface area of the square pyramid, first we find the base area by multiplying 12 by 12 to get 144. Then we find the area of each triangle face by using the formula (base x height) divided by 2, which is (12 x 18) divided by 2, giving us 216. Since there are 4 triangular faces, we multiply 216 by 4 to get 864. Finally, we add the base area and total triangular area together to get the total surface area of the square pyramid, which is 1008 square units.
