Answer: 17 feet

Explanation:

Given : Ms.lu is adding a new room to her house. The room will be a cube with volume 4,913 cubic feet.

Let s be the side of the square-room.

We know that the volume of a square is given by :-

$\text{Volume}=s^3$

Then for the given room we have

s^3=4,913

Taking cube root on both sides , we get

$s=\sqrt[3]{4913} =17$

Hence, the length of the new room = 17 feet.
