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.
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.
It increases nine-fold.
Area of a cube = 6 X side X side since all sides of cube are equal.

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 !
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!
Area of a cube = 6 X side X side since all sides of cube are equal.
First you can use the volume to determine the side legnth of a cube. The legnth of a sideis equal to the cube root of its volume. In this case the volume is 125 and the cubed root of 125 is 5. So the legnth of a side is 5. The area of one side of the cube is equal to the width times the height. In this case, the area of the side is 5 times 5, or 25. The surface area is the area of all sides of the cube. The cube has 6 sides, each with an area of 25. So the surface area is 6 times 25 or 150. The reduced equation would be SA = 6 times (Volume to the 2/3 power)
To find the surface area of a square (or rectangle) you multiply the length times the width. Then to get the total area of a cube you add up the surface areas of all the square sides it has. I hope you can figure it out from there.
It is the area of the exposed surface. So if you take a cube, the surface area is the sum of the areas of each of the 6 faces. They are all the same in the case of a cube. In general, add up the surface area of each exposed surface and this is the total surface area.
