Given that a cube has edges measuring 6 centimeters each.
We know that cube is like a box whose faces are square.
So the surface area is given by formula

where x represents side length of the cube.
Given that side length of the cube = 6 centimeters
so plug this value into above formula:
Surface area

Surface area

Surface area = 6(36)
Surface area = 216
Hence final answer is 216 square centimeter.
