not a cube a cube has all equal sides
A cube has all sides equal. The base area of cube = any surface of cube. All sides are squares (since all lengths are equal). So, the base area of cube = length * breadth.
It increases nine-fold.
Surface Area of a Cube = 6 a 2(a is the length of the side of each edge of the cube)In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.
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.
not a cube a cube has all equal sides
A cube has all sides equal. The base area of cube = any surface of cube. All sides are squares (since all lengths are equal). So, the base area of cube = length * breadth.

SA = area of all sides added up. 6 Faces on a cube. 82 = 64. 64 x 6 = 384 The surface area of an 8" cube is 384"
The bulk of the question is irrelevant ! If all you need is the surface area of the 3-inch cube, simply multiply 3 x 3 x 6 to give 54 square inches !
Well, isn't that a happy little question! To find the surface area of a cube, you simply need to calculate the area of all six sides and add them up. Since all sides of a cube are the same, you can find the area of one side by squaring the length of one side. So, for a 3-inch cube, the surface area would be 6 sides x (3 inches x 3 inches), which equals 54 square inches. Happy painting!
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!
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.
Area of a cube = 6 X side X side since all sides of cube are equal.
Each side is 11.6 cm X 11.6 cm, or 134.56 cm, X 6 sides = 807.36 cm.
