The Face Area of a Tetrahedron calculator computes the area of one face of a tetrahedron based on the length of a side (a).     Regular Tetrahedron

INSTRUCTIONS: Choose units and enter the following:

• (a)  This is the length of an edge

Tetrahedron Face Area (A): The calculator returns the area (A) in square meters.  However, this can be automatically converted to other area units via the pull-down menu.

Tetrahedron Calculators

• Area of the face of a tetrahedron.
• Surface area of a tetrahedron.
• Volume of a tetrahedron
• Mass or Weight of a tetrahedron
• Height of a tetrahedron.
• Roll a virtual tetrahedron (4 sided) dice

The Math

A regular tetrahedron is a three dimensional shape with four vertices and four faces.  The lengths of all the edges are the same making all of the four faces identical equilateral triangles.

The formula for the face area of a Tetrahedron is:

• `A = sqrt(3)/4 *a^2`

where:-

• A = Face Area (the surface area of any of the four sides)
• a = length of any edge. They are all the same.
