Assuming you mean 4 centimeters on an edge:
Each face will be 4cm x 4 cm with an area of 16 cm2. Since a cube has 6 faces, the total surface area will therefore be 6x16 cm2 = 96 cm2

Each side has surface area of 3X3 = 9 cm 6 sides X 9 cm/side = 54 cm
The surface area of a cube with side lengths 52.5cm is 16,540cm2
The surface area of a 7 cm cube is 294 cm2
216 squared cm
The surface area of a cube with sides of 4 cm is 6*42 square cm = 96 sq cm. The surface area of a cube with sides of 2 units is 6*22 square units = 24 sq units.
