Answer 2

Answer:

Step-by-step explanation: I am guessing you mean the perimeter of one face of a cube.

A face of a cube is a square. And a square has 4 sides so if the perimeter of a face of a cube is 40 cm, the length and breadth is equal to 10 cm, so the area of one face of a cube is 100. If the area of one face of a cube is 100 cm, then the area of 6 faces if 100*6 which is 600.

Hope this helps
