# What are good formulas for finding the surface area of a triangular prism?

(trianges could be scalene, isosceles, or equilateral)? (a formula for each)

bh/2xlxw is the formula for surface area of a triangular prism

for surface area it’s SA=bh+2(lengthside)+lengthbase

for volume it’s V=1/2(base*height)length

Well, there isn’t one specific formula for a certain type of a triangle. But the formula for the surface area of a triangular prisim is, sa=pi(3.14)x 1/2bxhx2 +lxw

I know how to find the surface area but how do I find that unknown measure so I can then find the surface area?

The surface area = 2 × area of base + perimeter of base × height

Base shape: Triangle: base ‘b’, height ‘h’, and sides S1, S2 and S3 Area of base: ½ b×h Perimeter of base: S1+ S2 + S3 Surface area = bh + (S1+ S2 + S3)H
