Machine PrecisionGoverning Mathematical Formula:
Volume = Base Area · Length | Total Area = 2 · Base Area + (a + b + c) · Length
Step-by-Step Mathematical Derivation
1
Uniform Cross-Section Volumetric Extrusion
The volume of any right prism equals the area of its base polygon multiplied by its length: A_base = ½ · b · h. Volume V = A_base · L = ½ · b · h · L.
2
Lateral Wall Area
Assuming an isosceles triangular cross-section with slanted leg s = √[(b/2)² + h²], the perimeter is P_base = b + 2s. Lateral Area = P_base · L.
3
Total Closed Net
Total Area = (2 × A_base) + Lateral Area.

Frequently Asked Questions
What is the optical dispersion property of an equilateral glass prism?
Isaac Newton proved in 1666 that a triangular glass prism refracts white sunlight into its constituent spectral colors because the refractive index of glass varies inversely with wavelength (Snell's Law dispersion).
How many vertices, edges, and faces does a triangular prism have?
A triangular prism has 5 faces (2 triangular bases + 3 rectangular sides), 9 edges, and 6 vertices, satisfying Euler's polyhedral formula V - E + F = 6 - 9 + 5 = 2.
