The inequalities about the volume of the unit ball $\Omega_n$ in $\mathbb{R}^n$ were studies by several authors, especially Horst Alzer has a great contribution to this topic. Thereafter many authors produced numerous papers on this topic. Motivated by the work of the several authors, we make a contribution to the topic by giving the new inequalities about the volume of the unit ball $\Omega_n$. Our inequalities refine the recent results existing in the literature.
Keywords: inequalities, gamma function, psi function, volume of the unit ball.
