Formula

volume = (sqrt(2) / 3) x edge^3

A regular octahedron can be treated as two congruent square pyramids joined at the base.

Example

Edge Length 6 gives Volume 101. 82.

Check

Rounding an intermediate value too early when the output feeds another step.
Using the right formula with the wrong measurement label or axis.
