  We investigate the dependence on the dimension in the inequalities that
relate the volume of a closed submanifold $M^n\subset \mathbb{R}^N$ with its
$l^\infty$-width $W^{l^\infty}_{n-1}(M^n)$ defined as the infimum over all
continuous maps $\phi:M^n\longrightarrow K^{n-1}\subset\mathbb{R}^N$ of
$sup_{x\in M^n}\Vert \phi(x)-x\Vert_{l^\infty}$. We prove that
$W^{l^\infty}_{n-1}(M^n)\leq const\ \sqrt{n}\ vol(M^n)^{\frac{1}{n}}$, and if
the codimension $N-n$ is equal to $1$, then $W^{l^\infty}_{n-1}(M^n)\leq 3\
vol(M^n)^{\frac{1}{n}}$.
  As a corollary, we prove that if $M^n\subset \mathbb{R}^N$ is essential, then
there exists a non-contractible closed curve on $M^n$ contained in a cube in
$\mathbb{R}^N$ with side length $const\ \sqrt{n}\ vol^{\frac{1}{n}}(M^n)$ with
sides parallel to the coordinate axes. If the codimension is $1$, then the side
length of the cube is $12\cdot vol^{\frac{1}{n}}(M^n)$.
