The surface area of a cube is 54 square centimeters. Divide it into small cubes with an edge length of 1 cm. The sum of the surface areas of these small cubes is The surface area of a cube is 54 square centimeters. Divide it into small cubes with an edge length of 1 cm. How many square centimeters has the sum of the surface areas of these small cubes increased compared with the surface area of the original cube?

The sum of the surface areas of these small cubes is The surface area of a cube is 54 square centimeters. Divide it into small cubes with an edge length of 1 cm. How many square centimeters has the sum of the surface areas of these small cubes increased compared with the surface area of the original cube?

54 / 6 = 9 each face is 9 square centimeters, so the edge length is 3cm, so it can be divided into 3 * 3 * 3 = 27 small squares, and the surface area is 27 * 6 = 162, increasing 162-54 = 108
