To solve this, we equate the formulas for the volume and surface area of a cube.

1. Formulas: Volume of a cube ($V$) with side length $a$ is $V = a^3$ . Total Surface Area ($A$) of a cube with side length $a$ is $A = 6a^2$ (since a cube has 6 faces) .

2. Calculation: Given condition: Numerical value of Volume = Numerical value of Surface Area. $a^3 = 6a^2$ Since the side length $a$ cannot be zero, we divide both sides by $a^2$: $a = 6$ Now, calculate the volume using $a = 6$: $V = 6^3 = 6 \times 6 \times 6 = 216$

3. Conclusion: The volume of the cube is 216 cubic units.
