Prism Calculator
Calculate volume and surface area of triangular, rectangular, and polygonal prisms
About this calculator
The Prism Calculator is a versatile tool that computes the volume and surface area of various prism types including triangular, rectangular, and polygonal prisms. This calculator is essential for students, engineers, architects, and professionals who need accurate geometric calculations for construction projects, material estimation, or academic purposes. It eliminates manual calculation errors and saves time by providing instant, precise results for complex three-dimensional shapes with consistent cross-sectional areas.
How to use
Select your prism type (triangular, rectangular, or polygonal) from the dropdown menu. Enter the required dimensions such as base measurements, height, and side lengths in the input fields. Click the calculate button to instantly view both the volume and surface area results with detailed breakdowns.
Frequently asked questions
What's the difference between volume and surface area?
Volume measures the space inside a prism (cubic units), while surface area measures the total area of all faces (square units).
Can I calculate irregular polygonal prisms?
Yes, the calculator supports regular polygonal prisms. For irregular shapes, you'll need the area of the base polygon.
What units does the calculator use?
The calculator works with any consistent unit system. Results will be in the same units you input.
