The original length of the edges are equal to 2 cm.
Step-by-step explanation:
The volume of a cube is given by the following expression:
Where "a" is the length of each edge of the cube. Assuming that the original cube had a length of "x", then its volume would be:
Since the edges of the cube got scaled by a factor of 2, then the new edges are "2*x" and the volume is:
The original length of the edges are equal to 2 cm.
