If surface area and volume of a cube are numerically equal then the side of the cube is
Let x cm be the cube's side.
The cube's surface area is equal to 6x^2.
The cube's volume is equal to x^3.
Considering that volume = surface area, 6x^2 = x^3
Assuming that x is not equal to zero, divide both sides by x^2:
6 = x
Thus, the cube's side measures 6 cm.
