This thesis is a study on the volumes of cusped hyperbolic 3-manifolds with a compact totally geodesic boundary. Its main goal is to identify the smallest member in the class of such manifolds. Author outlines a process that zeroes in on a manifold which was preidentified as a candidate for the smallest manifold in this class. Most of the computations are parameterized in terms of $x_1$ ; a variable closely associated with the volumes of manifolds with geodesic boundary. Chapter 3 describes the construction of a lower bound for the volumes of manifolds in $\mathcal{N}_{c,c}$ in terms of their $x_1$ values. In chapter 4, the relation between the geometry of a manifold in $\mathcal{N}_{c,c}$ is leveraged to obtain a lower bound for its $x_1$ value. Results in those two chapters yield an interval of possible $x_1$ values for the smallest manifold in $\mathcal{N}_{c,c}$. The remainder of the thesis investigate this interval extensively.
