Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.

SA = 54 square inches.

The surface of the cube is 6 times this length squared - 6L2.

A cube has 6 faces. Each face will be 7.5 times 7.5 = 56.25 square inches. Therefore the surface area of the culbe will be 6 times 56.25 = 337.5 square inches.

If a cube measures 5 inches on an edge, then each face of that cube is a square measuring 5 inches by 5 inches, having an area of 25 square inches.

Surface area of a cube A = 6*L^2 where L is the length of each side. L = sqrt(A/6) = 8.

Assuming your cube is actually a cube, each plane (face) would be 36 square inches. Multiply by six for your total surface area.

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.

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.

SA = 54 square inches.

If the area of a cube surface is 96 square inches, then each of six sides has an area of 16 square inches and the length of each side is 4 inches. The volume is 4 x 4 x 4 = 64 cubic inches
