Formula

surface area = sqrt(3) x edge^2

The four faces of a regular tetrahedron are congruent equilateral triangles.

Example

Edge Length 6 gives Surface Area 62. 35.

Check

Using the right formula with the wrong measurement label or axis.
Switching between degrees and raw ratios without noticing the change.
