Tetrahedron - Surface Area

The Surface Area of a Tetrahedron calculator computes the surface area of a regular tetrahedron based on the length of a side (a).     Regular Tetrahedron

INSTRUCTIONS: Choose units and enter the following:

• (a)  Length of Edge

Tetrahedron Surface 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.

The Math

A regular tetrahedron is a three dimensional shape with four vertices and four faces that are all identical equilateral triangles.

The formula for the Surface Area of a Tetrahedron is:

• `A = sqrt(3)*a^2`

where:-

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