![]() To calculate the volume, all you have to do is find the area of one of the triangular bases and multiply it by the height of the prism. We say a triangular prism is semi-regular if its triangular bases are equilateral and the other faces are squares, instead of a rectangle.įormula to Calculate Volume of a Triangular Prism.The steps to determine the volume of the pentagonal prism are: Step 1: The area of the base of the pentagonal prism is found using the formula, 5/2ab 5/2 × 5 × 4 50 square feet. It has two triangular bases and three rectangular sides. The volume of the pentagonal prism is obtained using the formula V 5/2 × abh.The base of the triangle is 2cm 2cm and the height of the triangle is 3cm 3cm. 2 Calculate the area of the triangular cross-section and substitute the values. A triangular prism has a total of 9 edges, 5 faces, and 6 vertices which are joined by the rectangular faces. Volume of a triangular prism Area of triangular cross section x length.Triangular prism has a triangular cross section.This kind of a prism has its base formed by an irregular polygon eg. This kind of a triangular prism has its base formed by an equilateral triangle. Triangular prisms can also be categorized on the type of the triangle that forms its base. This prism’s bases are not perpendicular to the lateral faces and do not meet at right angles. This is a prism whose bases are perpendicular to the lateral faces, meaning they meet at right angles. ![]() Triangular prisms can then be classified based on how their bases and lateral faces intersect. In this case the two ends also known as the bases are triangular in shape. ![]() A triangular prism is a three-dimensional solid object in which the two ends are exactly of the same shape. Ahead of discussing how to calculate the volume of a triangular prism, let’s define what it is.
