Answer:

3.10 m

Step-by-step explanation:

The bedroom needs to be 30 cubic meters when finished.

We need to find the dimensions of the room.

The volume of a cube is given by :

[tex]V=a^3[/tex]

Where

a is the side of the cube

So,

[tex]a=(V)^{1/3}\\\\a=(30)^{1/3}\\\\a=3.10\ m[/tex]

So, the dimension of the room is 3.10 m.
