The formula for finding the surface area of a triangle is bh divided by 2

find the surface area of one face, and then do the others. I can't tell you to muliply because your triangular pyramid might not be equal.

just remember the formula for finding a triangle is bh divided by 2(base of the prism, multiply with the height of prism and then divided by 2)
