To find the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6 \times (s^2) \]
where \( s \) is the length of one side of the cube.
In this case, the side length \( s = 7 \) inches.
Calculating:
\[ \text{Surface Area} = 6 \times (7^2) \] \[ = 6 \times 49 \] \[ = 294 \text{ in}^2 \]
So, the surface area of the cube is 294 in².
