Answer:
Surface area of the cube will be 75264 square feet.
Explanation:
We know there are six sides in a cube. Therefore surface area of the cube is the addition of area of all six sides.
Since each side of a cube is a square having all sides equal in size.
Therefore area of one side of a cube = Side² 
and area of the cube = 6 × side² 
Now by putting area of the cube = 6 × 112² = 75264 square feet.
