  • In this article, we solve the relative isoperimetric problem in $[0,1]^3$ for orthogonal polyhedra. Up to isometries of the cube or sets of measure $0$, the minimizers are of the form $[0,ε]^3$, $[0,ε]^2 \times [0,1]$, or $[0,ε] \times [0,1]^2$ for some $ε> 0$. This should be compared to the conjectured minimizers for the unconstrained relative isoperimetric problem in $[0,1]^3$, which are (up to isometries and sets of measure $0$) of the form $\left( B^3(ε) \right) \cap [0,1]^3$, $\left( B^2(ε) \times [0,1] \right) \cap [0,1]^3$, or $[0,ε] \times [0,1]^2$ for some $ε> 0$. Here, $B^k(ε)$ is the closed ball in $\mathbb{R}^k$ of radius $ε$ centered at the origin.
