About Triangular Prism Surface Area
Formula:
SA = 2 × Base Area + Lateral Area
Base Area = √(s(s-a)(s-b)(s-c))
Lateral Area = (a + b + c) × h
where s = (a + b + c) / 2
Properties:
- Has 5 faces (2 triangular bases + 3 rectangular sides)
- Has 6 vertices and 9 edges
- Lateral faces are rectangles
- Base faces are congruent triangles
