surface area of a regular pyramid formula

The formula to calculate the surface area of a regular pyramid is:

Surface Area = (1/2) * Perimeter of the base * Slant height + Area of the base

Where:
- Perimeter of the base is the sum of all the sides of the base
- Slant height is the distance from the apex of the pyramid to the center of one of the base's edges
- Area of the base is the area of the base shape, such as square, rectangle, triangle, etc.
