There is no single formula for a cube. There are different formulae for its surface area, its volume, and so on.
Acube -bcube
This is the formula: (a3)+(b3)=(a+b)(a2-ab+b2)
Then you calculate the cube root!
(a+b)cube = a cube + b cube + 3a square b + 3ab square
If 'S' = length of the cube's side, then its volume = S3 .
The surface area of a cube is 6 * side^2
The formula for a volume of a cube is length x width x height. For example, if all sides of a cube were 3 inches, then the volume is 9 inches cubed.
S=ph+2b
6B
6 a 2
m = n³
This should be solved in two steps. 1) Use the formula for the area of a cube, and solve for the length of a side of the cube. 2) Using this length, it is easy to find out the volume, with the formula for the volume of a cube.
