While triangles are fundamentally 2-dimensional shapes, the concept of "triangle volume" typically arises when we consider a prism or a pyramid with a triangular base. This calculator addresses the volume of a triangular prism, which is a 3D shape formed by two parallel triangular bases connected by three rectangular faces.
The Formula
The volume of any prism is calculated by multiplying the area of its base by its height (or depth, in this context). Since the base of a triangular prism is a triangle, we first need to calculate the area of that triangle.
Area of a Triangle: The area of a triangle is given by the formula: Area = 0.5 * base * height
Volume of a Triangular Prism: To find the volume, we multiply this area by the depth (or length) of the prism: Volume = Area of Triangle * Depth Volume = (0.5 * base * height) * depth
In this calculator, 'base' and 'height' refer to the dimensions of the triangular face, and 'depth' refers to the third dimension that gives the shape its volume. All measurements should be in the same unit (e.g., centimeters, inches, meters). The resulting volume will be in cubic units (e.g., cubic centimeters, cubic inches, cubic meters).
Common Use Cases
Construction and Engineering: Calculating the amount of material needed for triangular beams, supports, or structural components.
Manufacturing: Determining the volume of objects with triangular prism shapes, such as certain types of packaging or industrial parts.
Geometry and Education: A fundamental tool for students learning about 3D shapes and volume calculations.
Design: Estimating material quantities for architectural elements or product design.
Ensure all your input measurements are consistent in units for an accurate calculation.

}
var triangleArea = 0.5 * base * height;
var volume = triangleArea * depth;
resultDiv.textContent = volume.toFixed(2) + " cubic units";
resultDiv.style.backgroundColor = "var(–success-green)"; /* Green for success */
