Approximately 50.265 square inches.
Each face of the cube would have an area of 4*4 = 16 sq inches. A cube has 6 faces so the total surface area = 6*16 = 96 sq inches.

Invalid conversion: square inches is a measure of area and inches is a measure of length or distance.If each side of a square is 10 inches long, the area of the square will be 100 square inches. (10*10=100)For any rectangle with an area of 100 square inches, the length of the short side times the length of the long side must total 100.(For instance, a rectangle 4 inches by 25 inches: 4*25=100)
