Each edge measures two units.
Total Surface Area of Cube is 6a2 . Here "a" is the "length of each side" of the cube.
The surface area is quadrupled.
The surface of the cube is 6 times this length squared - 6L2.
The surface area of a cube can be calculated by finding the area of each of the cube's six square faces and adding them together. Since all sides of a cube are equal, the area of one face is the side length squared. Therefore, the surface area of a cube with a side length of 8mm is 6 times 8mm squared, which equals 384 square millimeters.
-- Surface area tells how much of a table a 2D shape will cover.-- Volume tells how much water a 3D shape will hold.-- It may be a bit confusing if you hear someone mention "the surface area of a cube".What they're talking about is not really the surface area of the cube, but the surfacearea of the faces of the cube ... the area of the construction paper or sheet metal thatyou'd need in order to build the cube.In the case of the cube ...-- The area of one face is the 'square' (length x length) of the length of each edge.-- The total area is 6 times the area of each face.-- The volume is the 'cube' (length x length x length) of the length of each edge.
Total Surface Area of Cube is 6a2 . Here "a" is the "length of each side" of the cube.
The surface area is quadrupled.
The surface area of a cube is 6*s2 where s is the length of each side (or edge).
If each edge of a cube is w, then the area of each face of the cube is w2 .Since the cube has 6 faces, its total surface area is 6w2.The volume of the cube is w3 .

Surface Area of a cube is equal to the sum of the area of it sides. Each of its sides are square of side length a. Each side has area of a2. There are 6 sides on a cube. a2 + a2+ a2+ a2+ a2+ a2 = 6a2 Therefore: Surface area of a cube is 6a2
surface area of cube=6*side*side =6*7.2*7.2
ok, so think about it. a cube has 6 sides. The surface area is the area of the surface of all 6 sides combined, so you divide the surface area by 6. This gives you the area of each square on each side. Then square root the answer because the area of a square is the side length squared. Now you have the edge length!
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.
