There are 6 sides to a cube. One side of the cube would need x strips of 2cm wide tape to cover a 10cm x 10cm square. Thus, each strip will be 10cm long and we need 2x = 10. Therefore, it will take 5 strips of tape to cover one side. Since the cube has 6 sides, we need 5(6) = 30 strips of 10cm long tape or 300cm of tape to cover the cube.
