The formula to find the surface area of a regular triangular pyramid is given as:
Surface Area = ½ * (Perimeter of the base) * (Slant height) + (Area of the base)
where:
- Perimeter of the base is the sum of the lengths of all sides of the base triangle
- Slant height is the length of the line segment from any vertex of the pyramid to the centroid of the base triangle
- Area of the base is the area of the base triangle.
It's important to note that a regular triangular pyramid has an equilateral triangle as its base.
