Answer:
The surface area of the cube is 648.96 sq in.
Step-by-step explanation:
This problem is made a lot easier by the fact that it's a cube.
So we first calculate the area of one of the faces. The length of the side of the side is 10.4 inches, and <em>10.4 * 10.4 = 100.16.</em>
There are six faces, so we multiply the area of 1 face by 6. <em>100.16 * 6 = 648.96. </em>
Therefore, the surface area of the cube is 648.96 sq inches.
