Get the square root of the result and divide it by 4.Multiply the result from the above two steps.And add two sides and subtract the third side from the sum repeat this process three times with three different sides.Get three sides of the triangle from the question.Triangular Prism Top, Bottom Surface Area: Divide the product by 2 to check the volume.Multiply prism height, triangle height, and base.Obtain the prism height, triangle base, height.Multiply the result with the value from step 2 to get the volume.Add all sides of the triangle and add any two sides and subtract the third side from the sum.Find out the triangle sides, and prism height.Use these easy steps to get the result quickly. If prism volume, height are given, thenĪ, b, c are the side lengths of a triangleĪ top is the top surface area of a triangular prismĪ bot is the bottom surface area of a triangular prismĪ lat is the lateral surface area of a triangular prismīelow given is the simple step-by-step process which is useful while solving the triangular prism unknown parameters.If triangle sides, lateral surface are being given, then.If bottom triangle side, height, and prism height are given, then.Total Surface Area of a Triangular Prism Formula.Lateral Surface Area of a Triangular Prism Formula.Bottom Surface Area of a Triangular Prism Formula.Top Surface Area of a Triangular Prism Formula.You can check out the volume, total surface area, lateral surface area, top, and base surface area formulas on this page. Where B is the area of a triangular base and h is the height (the distance between the two parallel bases) of the triangular prism.Get the useful formulas of a triangular prism in the following sections. The volume, V, of a triangular prism is the area of one of its bases times its height: Often, a regular triangular prism is implied to be a right triangular prism. Therefore, if the bases of the triangular prism are equilateral triangles, it is a regular triangular prism. A regular prism is defined by a prism whose bases are regular polygons. Triangular prisms can also be classified based on the type of triangle that forms its base. Otherwise it is an oblique triangular prism. If the bases are perpendicular to the lateral faces, meaning they meet at right angles, it is a right triangular prism. Triangular prisms can be classified based on how their bases and lateral faces intersect or meet. Classifying triangular prisms based on their intersecting faces This is true for any parallel cross section of a triangular prism. They are congruent to the two triangular bases of the triangular prism since they are formed by cross sections that are in planes parallel to the bases. Two triangular cross sections for the triangular prism are shown in green above. It also has 9 edges and 6 vertices.Īny cross section of a triangular prism that is parallel to the bases forms a triangle that is congruent to the bases. Triangular prisms, like the one above, have a total of 5 faces, with 2 bases and 3 lateral faces. A vertex is the point of intersection of three edges. An edge is a line segment formed by the intersection of two adjacent faces. There are three lateral faces for a triangular prism. The lateral faces (sides that are not bases) are parallelograms, rectangles, or squares. Properties of a triangular prismĪ triangular prism is a polyhedron that has two parallel and congruent triangles called bases. In the figure below are three types of triangular prisms. Home / geometry / shape / triangular prism Triangular prismĪ triangular prism is a prism with triangular bases.
