The surface area \( S \) of a cube can be calculated using the formula:
\[
S = 6s^2
\]
where \( s \) is the length of a side of the cube. In this case, the side length \( s \) is 3.5 inches.
First, calculate \( s^2 \):
\[
s^2 = (3.5)^2 = 12.25
\]
Now, substitute \( s^2 \) into the surface area formula:
\[
S = 6 \times 12.25 = 73.5
\]
Therefore, the surface area of the cube is \( 73.5 \) square inches.
