Answer: 17 feet
Step-by-step 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.
