What the formula?

The correct answer should be C to this question
A two-dimensional net is useful because it flattens the 3-d figure so that you can see all the faces of the figure. You can calculate the area of each face to find the surface area.
The total area painted was 480 inches. 4 cubed is 64, 8 cubed 512. 512 +64= 576. Then you subtract two sides of the 4 inch square because the bottom is not painted and one side is pushed against the 8 inch cube. That means 576-32= 544. Then you subtract the bottom of the 8 inch cube, which means 544-64= 480.
