I: \(\overrightarrow{a}\), \(\overrightarrow{b}\) and \(\overrightarrow{c}\) are co-planar for p = 1/5

II: If \(\overrightarrow{a}\), \(\overrightarrow{b}\) and \(\overrightarrow{c}\) are coterminous edges of a parallelepiped, its volume for p = 5 is 24.

Which of the following statement(s) is/are correct.
