First, if a square with side √A has the same area as an L-by-W rectangle, then as illustrated in Figure 5.1, the square root of A is in between L and W.

How to approximation cuboid to cube ?

Rf) approximation rectangle to square is 

The act of computing the square root of a positive number A is the act of “building” a square
with area A. Thinking along these geometric lines, we make a pair of observations. First,
if a square with side √A has the same area as an L-by-W rectangle, then as illustrated
in Figure 5.1, the square root of A is in between L and W. Second, we can make any
given rectangle “more square” by replacing L with Lnew = (L+W)/2  and W with Wnew =
A/Lnew. The process can obviously be repeated:
