54 cm2
I thought the answer was: 6 x 3squaredcmsquared
Suppose the side of the cube is s cm. Then s3 = 27 so that s = 3 cm. Each of the six faces of the cube is a 3cm * 3cm square. 6 squares, each with a surface area of 9 cm2 makes a total surface area of 54 cm2
The area of one face of a 3cm cube is the area of a 3cm square. That's 3 x 3 = 9cm2.
