Since cube has all faces as Squares
perimeter of each face P = 22.2
as we know perimeter of a square is P = 4 * ( Sides of a square )
let the sides of the square be 'x'
Hence , 22.2 = 4 * x
=> x = 22.2/4
=> x = 5.55
hence the edge's length is 5.55
Note : if the length from edge to edge is asked then
Length of the Diagonal for a cube =
Hence we get edge to edge length as
√3 * 5.55 = 9.612

Answer:
This is true when the shape is a cube because all the faces are equivalent. This isn't true when it is a rectangular prism because some faces have areas larger than other faces.
