Triangular Prism Calculator

Solve for all geometric properties of a triangular prism. This tool provides both volume and surface area results based on your triangle's dimensions.

Triangle Base (b)*

Triangle Height (h)*

Prism Height / Length (L)*

Side a (Optional for SA)

Side c (Optional for SA)

Volume (V) = (1/2 × b × h) × L Surface Area (SA) = (b × h) + (a + b + c) × L

For a prism with base triangle (b=6, h=4) and prism length L=10: • Volume: (0.5 * 6 * 4) * 10 = 120 units³ • Base Area: 12 units²

What is a triangular prism?

A triangular prism is a three-dimensional solid with two identical triangular bases and three rectangular lateral sides.

How do you calculate the volume of a triangular prism?

The volume is the area of the triangular base multiplied by the height (length) of the prism. Formula: V = (1/2 × base × height_of_triangle) × height_of_prism.

What is the surface area formula?

The total surface area is the sum of the areas of the two triangular bases plus the areas of the three rectangular sides. Formula: SA = (2 × base_area) + (perimeter_of_base × height_of_prism).

Can I use this for any type of triangle?

Yes, as long as you know the base and the height of the triangular face, this calculator will work for equilateral, isosceles, and scalene triangles.
