Math

Right Triangular Prism: calculate results from explicit inputs, with a formula and worked example.

Formula

volume = triangle area × length; surface = 2 triangle area + triangle perimeter × length

Example Calculation

Example inputs
  • Side a: 3 units
  • Side b: 4 units
  • Side c: 5 units
  • Prism length: 10 units

A 3–4–5 triangular base and length 10 give volume 60 and surface area 132.

Frequently asked questions

How do I use this calculator?

Enter side a, side b, side c, prism length. The result updates automatically. Use Reset to restore the example values.

What method does it use?

volume = triangle area × length; surface = 2 triangle area + triangle perimeter × length. Euclidean geometry. Use one consistent length unit; areas and volumes use its square and cube. Degenerate shapes are rejected. Very thin shapes may lose floating-point precision.

Why might a rounded result differ?

The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.

Are my inputs saved online?

No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
