Ms. Lu is adding a new room to her house. The room will be a cube with a volume of 4,913 cubic feet. What is the length of the new room?

Answer :

The length of the new room is 17 feet.

To find the length of the new room, which is a cube, we need to determine the cube root of the volume. The volume of a cube is given by [tex]\( V = s^3 \)[/tex], where[tex]\( s \)[/tex] is the length of one side of the cube. We are given that the volume [tex]\( V \)[/tex] is 4,913 cubic feet.

To find the side length [tex]\( s \)[/tex] , we take the cube root of the volume:

[tex]\[ s = \sqrt[3]{V} \][/tex]

[tex]\[ s = \sqrt[3]{4913} \][/tex]

[tex]\[ s = 17 \][/tex]

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 :-

[tex]\text{Volume}=s^3[/tex]

Then for the given room we have

[tex]s^3=4,913[/tex]

Taking cube root on both sides , we get

[tex]s=\sqrt[3]{4913} =17[/tex]

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