Answer:
The volume will increase 729 fold.
Step-by-step explanation:
If the length, width, and height of a cube all change by a factor of 9.
The answer is 729 fold, or 9 cubed.
As if original length is l
The original width is w
And original height is h
Volume = l x w x h
But when all change by a factor of 9, we get
9l x 9w x 9h
= 729 fold
Therefore, the volume will increase 729 fold.
