1. Calculate the area of the square base by raising the side length to the power of 2 (12 in this case): 12^2 = 144 square units.
2. Determine the perimeter of the square base by multiplying the side length by 4: 4 * 12 = 48 units.
3. Substitute the base area (144), perimeter (48), and slant height (18) into the formula to find the surface area:
Surface area = base area + 1/2 * perimeter * slant height
Surface area = 144 + 1/2 * 48 * 18
Surface area = 144 + 24 * 18
Surface area = 144 + 432
Surface area = 576 square units.
Therefore, the surface area of the square pyramid is 576 square units by following these steps.
1. Find the area of the square base by squaring the side length (12 in this case): 12^2 = 144 square units.
2. Calculate the perimeter of the square base by multiplying the side length by 4: 4 * 12 = 48 units.
3. Plug the base area (144), perimeter (48), and slant height (18) into the formula to find the surface area:
Surface area = base area + 1/2 * perimeter * slant height
Surface area = 144 + 1/2 * 48 * 18
Surface area = 144 + 24 * 18
Surface area = 144 + 432
Surface area = 576 square units.
Therefore, the surface area of the square pyramid is 576 square units by following these steps.
