Q:

How many edges does a triangular prism have?

A:

A triangular prism has nine edges. It consists of a triangular base, a translated copy of the base and three quadrilaterals, for a total of five faces and six vertices.

The surface area of a triangular prism can be calculated by taking the area of each of the five faces (two triangles and three quadrilaterals) and adding them together.

The volume of a triangular prism is the area of one of the triangles multiplied by the length of a quadrilateral (which represents the distance between the two triangles.) According to About.com, the formula is V = (1/2)bhl where b and h are the base and height of a triangle, and l is the length of a quadrilateral.

A triangular prism is a pentahedron. A pentahedron is a polyhedron with five faces.

A triangular prism has five faces, six vertices and nine edges. The face is the flat side of a solid figure, and it is typically in the form of a plane figure such as a rectangle, square or triangle, with the triangular prism having two triangular bases and three rectangular sides. Another type of prism is the rectangular prism, which has six rectangular faces, 12 vertices and eight edges.

To find the volume of a triangular prism, multiply the base area by the length of the prism. You need to know the base area and the length of the prism. Use a ruler, a pen, a divider, a piece of paper and a calculator.

The faces of a triangular prism are parallelograms while the two bases are triangles. This gives the prism three faces. In a regular prism, the faces are rectangles. However, some prisms lean to one side and are oblique.

The formula for the surface area of a triangular prism is SA = bh + (s1 + s2 + s3)H. In this formula, "b" is the triangle base, "h" is the triangle height, "s1," "s2" and "s3" are the three triangle sides, and "H" is the length of the prism.
