How to Calculate Triangular Prism
What is Triangular Prism?
A triangular prism has two parallel triangular faces (bases) connected by three rectangular faces. Volume = base area × length; Surface area = perimeter × length + 2 × base area. It appears in architecture, optics, and packaging.
Step-by-Step Guide
- 1V = (1/2 × b × h_triangle) × L (where L = prism length)
- 2SA = (b + s₁ + s₂) × L + 2 × (1/2 × b × h_triangle)
- 3For right triangular prism with sides a, b, c and length L:
- 4SA = (a + b + c) × L + base area × 2
Worked Examples
Input
Triangle base 6, height 4, prism length 10
Result
V = 120 cubic units
(0.5×6×4)×10 = 12×10 = 120
