answere: 216 inches
The formula for finding the area of a cube is s^3, where s refers to the length of one of its edges. This is because all the sides of a cube are equal. In this case, since one edge is given as 6 inches, all the other edges will also be 6 inches long. Therefore, the calculation for the area of the cube would be 6^3 or 6 x 6 x 6 which is equal to 216 inches.
