Answer:
2.83 inches longer
Step-by-step explanation:
The SA of a cube is 6s^2.
Therefore the length of the side of the 1200 square inches cube is approximately 14.142 inches long.
The length of the side of the 768 square inches cube is approximately 11.314 inches long.
If you subtract those two numbers, you get the difference in the lengths which is approximately 2.83 inches.
