Given a convex body $C\subset R^d$ and a positive real $\lambda$, any set of the form $\lambda C+x$ = {$~\lambda c+x|c\in C$} for some $x\in R^d$ is called homothetic copy of $C$. The number $\lambda>0$ is called as coefficient of homothety.

Let $C$ be a $d$-cube ($d$-dimensional cube) of side length 1. Now draw another cube $C'$ concentric and homothetic w.r.t. $C$ and having $\lambda= 1/2-\epsilon$ (or equivalently, $C'$ is of side $1/2-\epsilon$).

Now,

1) How many translated copies of $C'$ would be require to cover the annulus obtained between $C'$ and $C$?

2) How many translated copies of $C'$ would be require to cover $C$?
