# Diagonals of a Cube

**Geometry**Level 2

If a line makes angles \(\alpha\) , \(\beta\) , \(\gamma\) and \(\delta\) with the four body diagonals of a cube and the value of

\[\cos^2(\alpha) + \cos^2(\beta) + \cos^2(\gamma) + \cos^2(\delta)\] can be expressed as \(\frac{p}{q}\), where \(p\) and \(q\) are coprime integers, find the value of \(p + q\).

**Clarification:** Body diagonals of a cube are the diagonals which do not lie along any face of the cube.
