74 square inches
The bulk of the question is irrelevant ! If all you need is the surface area of the 3-inch cube, simply multiply 3 x 3 x 6 to give 54 square inches !

SA = area of all sides added up. 6 Faces on a cube. 82 = 64. 64 x 6 = 384 The surface area of an 8" cube is 384"
The surface area of a 1 inch cube is: 6 square inches.
Each of the 6 sides has a 6*6 square inch surface (36 square inches). You should now be able to complete the calculation for the entire cube yourself.
Each face of the cube would have an area of 4*4 = 16 sq inches. A cube has 6 faces so the total surface area = 6*16 = 96 sq inches.
Try it out. A cube with four-inch sides has a volume of 64 cubic inches. A cube with two-inch sides has a volume of 8 cubic inches. That's eight times less.
That would be a cube with 4 inch sides
Eight 4 inch cubes are needed to build and 8 inch cube.
If you double a 2-inch cube to a four-inch cube, its volume increases from eight cubic inches to 64 cubic inches.
