Given information

Note that given the volume of a cube with respect to its edge length is equal to half the surface area of the cube.

Step-by-step explanation

Step 1.

Know that the surface area of such a cube is equal to the area of one face of the cube multiplied by the number of faces on the cube.

Therefore,  

Observe that this surface area equation is double our equation for the rate of change in volume.

Hence, it is verified that the rate of change of the volume of a cube with respect to its edge length is equal to half the surface area of the cube.
