Tool Usage

Return to old version

Set the base and prism height, then click Calculate. Volume = base area × prism height. Surface area needs the base perimeter; if missing, a clear prompt is shown.

Formula reference

For a right triangular prism, where prism height is the perpendicular distance between the two bases.

VolumeV = base area × prism height

Base areaA = 1/2 × base × triangle height

Lateral areaS_lat= base perimeter × prism height

Surface areaS = 2 × base area + lateral area

Instructions

Software Usage Instructions

Select the base condition:Choose “Base and Height,” “Three Sides,” “Right Triangle Base,” “Equilateral Base,” or “Known Base Area” based on the known parameters.
Enter dimension parameters:Fill in the base, triangle height, three sides, right-angle sides, side length, or base area according to the current mode, and enter the height of the triangular prism.
Set units and precision:Select units such as mm, cm, m, in, ft, yd, and set the number of decimal places to keep in the result.
Add the base perimeter:When only the base and height are known, or only the base area is known, enter the base perimeter if you need to calculate the lateral area and surface area.
View calculation results:After clicking “Calculate,” you can view the volume, base area, perimeter, lateral area, surface area, calculation steps, and unit conversions.
Save and export:You can click “Save Settings” to keep commonly used parameters, or copy the results or download TXT and CSV files.

FAQ

A: Volume of a triangular prism = base area × prism height. If the base triangle’s base and height are known, then base area = 1/2 × base × triangle height.

A: Surface area requires the base area and base perimeter. When only the base and triangle height are known, the base area and volume can be determined, but the three sides of the triangle cannot be uniquely determined, so the base perimeter must be provided.

A: Three-side mode first checks whether the three sides can form a triangle, then uses Heron’s formula to calculate the base area. It also obtains the base perimeter for calculating the lateral area and surface area.

A: Just enter the two legs of the right triangle and the prism height. The tool will automatically calculate the hypotenuse, base area, base perimeter, volume, lateral surface area, and total surface area.

A: When the base area and prism height are known, the volume can be calculated. To calculate the lateral surface area and total surface area, the base perimeter is also required.

A: Yes. The tool displays the original results based on the selected length unit and provides common volume conversions such as cubic meters, liters, cubic centimeters, and cubic feet.
