Answer 1

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.
