A cube has six sides. Each one is a square. In this instance, the square has a side length of 5 cm and therefore an area of 25 square cm. 25 X 6 =150 square cm. (This answer has more significant digits than are justified by the side length stated with only one significant digit, but it may have been intended to be an integer and therefore to have as many significant digits as needed.)
125. studyisland.The volume of any cube is (length of one side)3The surface area is (length of one side)2 x 6 [since a cube has six sides]
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 .
If the surface area of a cube is 294cm^2, the length of one side is equal to the square root of (294/4), which is approximately 8.57cm.
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)
Divide the surface area by six. That will give you the area of one face, which will be a perfect square. The square root of that number will give you the length of a side. The cube of the side will be the volume.
Surface Area of Cube is 6 x a^2 where a is the length of one side of cube. Volume of Cube is a^3 where a is the length of one side of cube.
Total Surface Area of Cube is 6a2 . Here "a" is the "length of each side" of the cube.

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.
If you know the length of a side (a) , the surface area is 6a2
surface area of cube=6*side*side =6*7.2*7.2
The surface area is quadrupled.

The surface area of a cube is 6*s2 where s is the length of each side (or edge).
Total Surface Area = 6L2. Where L = the length of one side of the cube.
The surface of the cube is 6 times this length squared - 6L2.
