Answer 1

To find the surface area of a square pyramid, we need to add the area of the base and the area of the four triangular sides. The area of the base is 12 x 12 = 144 square units. Each triangular side has an area of (1/2) x base x height, so that’s (1/2) x 12 x 18 = 108 square units for one triangle. There are 4 triangles, so 4 x 108 = 432 square units. Now we add the base area: 144 + 432 = 576 square units. So, the surface area is 576 square units!
