formula for finding the volume of tetrahedrone is=sqrt(2)*side*3/4
if side is 3 then the volume is 9(sqrt(2))/4
A tetrahedron is a four sided polyhedron. Each face is a triangle. If it is a regular tetrahedron, then each face is an equilateral triangle.
Yes. A tetrahedron is a closed 3-d shape with 4 triangular faces. In a regular polygon, each of these is an equilateral triangle.
It depends on whether or not the tetrahedron is regular. There is nothing in the question to indicate that it might be regular. In that case the easiest way to calculate the surface area is to sum the areas of each of its 4 faces.
If the length of each edge is s cm then the area of each face is sqrt(3)*s/4 square cm. Since there are 4 such faces, the total area is sqrt(3)*s cm2.
Tetrahedron: It is the smallest "regular solid" (Edges=Faces+Corners-2), 4 faces, each one an equilateral triangle. 4 corners

No and Yes A regular tetrahedron does not have any faces that are perpendicular to each other. (Regular in this sense means all edges are equally long - all faces are equilateral triangles)You can construct a irregular tetrahedron with two or three perpencdicular faces. To make such a tetrahedron with three faces perpendicular, simply cut the corner of a cube.
A tetrahedron has 4 vertices and 4 sides. Each side is an equilateral triangle. * * * * * Each face is an equilateral triangle only if it is a regular tetrahedron; there is no reason to assume it is.
If the length of each edge is s cm then the area of each face is sqrt(3)*s/4 square cm. Since there are 4 such faces, the total area is sqrt(3)*s cm2.
you cannot do this on the plane. try proving this yourself. but a regular tetrahedron in space for example is an example where there four points equidistant from each other.
Sphere: 4/3*pi*r3 Tetrahedron: s3*sqrt(2)/12 Cube: s3 Octahedron: s3*sqrt(2)/3 Dodecahedron: s3*[15+7*sqrt(5)]/4 Icosahedron: s3*5/12*(3+sqrt(5) where r is the radius and s is the length of each edge.

Tetrahedron in geogmetry is composed of four triangular faces, three of which meet at each vertex.
A white phosphorus molecule is in the shape of a regular tetrahedron, that is a pyramid with an equilateral triangle for its base. At each corner of the molecule is a phosphorus atom.
A Platonic solid is a solid all of whose face are regular and congruent polygons.There are five of these:A Tetrahedron. Four faces, each an equilateral triangle.Ad InfoA Hexahedron (Cube). Six faces, each a square.An Octahedron. Eight faces, each an equilateral triangle.A Dodecahedron. Twelve faces, each a regular pentagon.An Icosahedron. Twenty faces, each an equilateral triangle.
