To calculate the surface area of a cube, you can use the formula:
\[ \text{Surface Area} = 6 \times ( \text{side length} )^2 \]
However, we need the side length of the cube to compute the surface area. Since the options given are in square inches and square feet, it's likely that the problem expects a specific size for the cube. If we assume a side length of 7 inches, you can calculate it as follows:
- Given that \( \text{side length} = 7 , \text{inches} \): \[ \text{Surface Area} = 6 \times (7)^2 = 6 \times 49 = 294 , \text{in}^2 \]
Thus, if the cube’s side length were 7 inches, the surface area would be 294 in².
From the options presented, the correct answer is:
294 in².
