The figure below shows the two kinds of triangular prisms. In an oblique triangular prism, the sides joining the bases are not perpendicular.The sides meet the triangular bases at right angles in a right triangular prism.The triangles at the base are also congruent and parallel. A right triangular prism is one where the sides are rectangles, which are congruent to each other.A triangular prism has triangles at its base, whereas a rectangular prism has rectangles.The total surface area of a triangular prism is the sum of the lateral surface area and twice the area of the triangular base.The volume is equal to the product of the length of the prism and the area of the triangular base.The triangular prism is said to be uniform if the triangles at the base are equilateral, and the sides are squares.It has five faces (three rectangles and two triangles), six vertices and nine edges.A triangular prism is a three-dimensional body having two triangular bases connected by three rectangular sides.A cylinder is a tube and is composed of two parallel congruent circles and a rectangle which base is the circumference of the circle.Given below are the main characteristics of a Triangular prism. To find the volume of a prism (it doesn’t matter if it is rectangular or triangular), we multiply the area of the base, called the base area B, by the height h. How do you find the volume of a prism and a cylinder?.How to find the surface area of Rectangular Prisms:įind the area of two sides (Length*Height)*2 sides.įind the area of adjacent sides (Width*Height)*2 sides.įind the area of ends (Length*Width)*2 ends.Īdd the three areas together to find the surface area.
