Triangular Prism Calculator
Enter the base, height and other two sides of the triangular part, and the length of the prism — you get the volume and total surface area. Diagram help: there are identical triangles at both ends, and the length is the distance between them.
How to use
- Enter the base and height of the triangle.
- Enter the other two sides of the triangle and the length of the prism.
- You get the volume and surface area (two triangular parts + three rectangular parts).
Note: Formulas: Volume = triangle area x length = (1/2 x b x h) x L. Surface area = 2 x triangle area + (b + side2 + side3) x L.
Good to know
- The prism needs all three sides of the triangular face plus the length (the distance between the two triangles).
- Volume comes from the triangular face area times the length; surface area counts both triangular ends plus the three rectangles.
- The two triangular ends must be identical for these formulas to hold.
- Use the same unit for every measurement so volume and area stay consistent.
Frequently Asked Questions (FAQ)
What does the triangular prism calculator find?
The volume and the total surface area of a triangular prism.
What inputs do I enter?
The base, height and the other two sides of the triangular face, plus the length of the prism (the distance between the two triangles).
What formulas does it use?
Volume = triangle area x length. Surface area = 2 x triangle area + (all three triangle sides) x length.
Do the two triangular ends have to be identical?
Yes. These formulas only hold when the two triangular faces are identical, and all measurements must use the same unit.
