To find the surface area of a cube, you need to calculate the area of each face and then add them all together. Since all faces of a cube are identical squares, you only need to calculate the area of one square and then multiply by 6 (as there are 6 faces in a cube).

The area of a square is calculated by multiplying the length of one side by itself. In this case, the length of one side of the square (and the cube) is 3cm.

Area of one face = 3cm x 3cm = 9cm^2

Since there are 6 faces in a cube, the total surface area of the cube is:

Surface area = 6 x 9cm^2 = 54cm^2

Therefore, the surface area of the cube is 54 square centimeters.
