Answer:
The length of an edge of a Rubik's cube is 5.55 cm .
Step-by-step explanation:
As given
The perimeter of each face of a Rubik's cube is 22.2 centimeters.
As in the cube all the sides are of equal length .
Perimeter represented the sum of all sides.
As each face of the cube is consist of 4 sides .
Thus
[tex]length\ of\ an\ edge\ of\ a\ Rubik's\ cube = \frac{Perimeter\ of\ each\ face}{Total\ number\ of\ edges\ in\ each\ face}[/tex]
Putting the value in the above
[tex]length\ of\ an\ edge\ of\ a\ Rubik's\ cube = \frac{22.2}{4}[/tex]
= 5.55 cm
Therefore the length of an edge of a Rubik's cube is 5.55 cm .
