How do you find the surface area of a triangular prism?

Answer 1

Surface = 2b + Ph (b is the area of the base P is the perimeter of the base)

OR

Surface Area= 1/2(B x h)(2) + (s1+s2+s3)h

OR

Surface Area= (B x h) + (s1+s2+s3)h

B= Base.

H= Height.

s1, s2, s3= Basically the perimeter of the base.

Remember: the base of a triangular prism is not always on the bottom.
