Formula Tetrahedron Area
$$A ~=~ \sqrt{3} \, a^2$$ $$A ~=~ \sqrt{3} \, a^2$$ $$a ~=~ \sqrt{ \frac{A}{\sqrt{3}} }$$
Area
$$ A $$ Unit $$ \mathrm{m}^2 $$ Area of a tetrahedron. A tetrahedron consists of four triangular faces and has four edges.
Side length
$$ a $$ Unit $$ \mathrm{m} $$ The length of a side of a tetrahedron. Since here the tetrahedron is a regular polyhedron, all sides are of equal length.
