Regular Tetrahedron Math

Because the surface area is the area of all 4 faces combined in order to find the area for one of the faces only we must divide the surface area by 4.

Regular tetrahedron math. The regular tetrahedron often simply called the tetrahedron is the platonic solid with four polyhedron vertices six polyhedron edges and four equivalent equilateral triangular faces it is also uniform polyhedron and wenninger model it is described by the schläfli symbol and the wythoff symbol is it is an isohedron and a special case of the general tetrahedron and the isosceles. In a regular tetrahedron the angle between any two faces is found to be. A regular tetrahedron is one in which the four triangles are regular or equilateral and is one of the platonic solids. The area of one of these faces is given by.

Where e is the edge length of the regular tetrahedron. Tetrahedra is a polyhedron composed of four triangular faces three of which meet at each vertex. θ cos 1 1 3 θ c o s 1 1 3 when you solve with a calculator it can be equated to. If the tetrahedron is a regular tetrahedron its volume is.

Rounding off to the nearest decimal. A regular tetrahedron has 4 triangular faces. The volume v of tetrahedron is. The total surface area s of a regular tetrahedron in terms of its edges e is volume of a tetrahedron.
