Question

The perimeter of each face of a Rubik's cube is 22.2 centimeters.What is the length of an edge of a Rubik's cube? This is dividing decimals

Answer 1

divide 22.2 by 4 since the perimeter is the outside and there are 4 edges 

Answer 2

The length of an edge of a Rubik's cube is 5.55 cm .

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

`length\ of\ an\ edge\ of\ a\ Rubik's\ cube = (Perimeter\ of\ each\ face)/(Total\ number\ of\ edges\ in\ each\ face)`

Putting the value in the above

`length\ of\ an\ edge\ of\ a\ Rubik's\ cube = (22.2)/(4)`

= 5.55 cm

Therefore the length of an edge of a Rubik's cube is 5.55 cm .
