To calculate the total surface area of the cube, we need to find the area of one face (since all faces of a cube are identical) and then multiply it by the total number of faces (which is 6 for a cube).
The area of one face of the cube is simply the length of one side squared:
14 inches x 14 inches = 196 square inches.
So the total surface area of the cube is:
6 x 196 square inches = 1,176 square inches.
Therefore, Allen will need 1,176 square inches of metal to create the cube.
