Enter the triangle base, triangle height, and the length (depth) of the prism. The calculator computes the volume, surface area, and triangular base area.
- Enter the triangle base. The base of the triangular cross-section.
- Enter the triangle height. The height of the triangular cross-section.
- Enter the prism length. How long (deep) the prism extends.
Volume = (1/2) * base * triangle height * length. The surface area includes both triangular faces plus the three rectangular sides.
About Triangular Prisms
A triangular prism is a 3D shape with two parallel triangular faces and three rectangular faces. It is one of the simplest prisms. The volume equals the area of the triangular base times the length. Triangular prisms appear in Toblerone boxes, tent designs, roof structures, and optical prisms that refract light into a spectrum of colors.
Frequently Asked Questions
What is the volume of a triangular prism?
Volume = (1/2) * base * height * length, where base and height define the triangular cross-section and length is the depth of the prism.
How do you find the surface area of a triangular prism?
Surface area = 2 * (triangle area) + (perimeter of triangle) * length. The triangle area is (1/2) * base * height, and the perimeter includes all three sides of the triangle.
What is a triangular prism?
A triangular prism is a 3D shape with two parallel, congruent triangular faces connected by three rectangular faces. It has 5 faces, 9 edges, and 6 vertices.
