Surface area = 6*7.252 = 315.375 sq inches.
54 square inches.
Surface area of a cube A = 6*L^2 where L is the length of each side. L = sqrt(A/6) = 8.
Each side has dimensions of 4 inches x 4 inches so each side has an area of 16 square inches. There are six sides to a cube so the overall surface area is 16 square inches x 6, which is 96 square inches.
Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.
