How to find the total surface area of a triangular pyramid

If it is a regular tetrahedron, that is, it is made up of 4 equilateral triangles,
just find the area of one of them, then multiply by 4
if the base is not congruent to each of the other 3, you have to find
the area of the base, then add on the sum of the other 3 congruent and isosceles triangles.
The actual calculations will depend on the data that will be given.
btw, the area of an equilateral triangle of side s will be
(√3 / 4)s^2
