A Cube, has all equal sides, namely, the length, width and height
are all equal to each other
so.. notice the picture added here
you have really, 6 squares, stacked up to each other at the edges
so...what is the Area of one of those squares?
well, if the sides are equal, let's say the side is "x" long, then
the Area is

well, you have 6 of those squares, thus

solve for "x", to get one side's length
From the z-table and at p67 or 0.67 (the decimal values in the table),
Z =0.44
See the attached photo (at the point where 0.6700 appears)
