<br>
Three particles with large scattering length display a universal<br>
spectrum of three-body bound states called "Efimov trimers". I
show<br>
the modification of Efimov trimers of three identical bosons
when<br>
placed inside a finite cubic box and compute the dependence of
their<br>
energies on the box size using effective field theory. The<br>
renormalization of the effective field theory in the finite
volume is<br>
explicitly verified. The study of the three-nucleon system
inside a<br>
finite cubic volume provides a tool for the understanding of
Lattice<br>
QCD results. I present results for the triton in a finite volume<br>
including a study of the triton spectrum at unphysical pion
masses.<br>
