What is the formula for finding the surface area of a regular triangular pyramid? ( 1 point)
The formula for finding the surface area of a regular triangular pyramid is:
Surface Area = (Base Area) + (Lateral Area)
The base area can be calculated using the formula of the area of an equilateral triangle:
Base Area = (s^2 * sqrt(3)) / 4
where s is the length of one side of the base.
The lateral area can be calculated by finding the area of each triangular face and summing them up.
Lateral Area = (s * l) / 2
where s is the length of one side of the base and l is the slant height of the pyramid.
