Solution

The correct option is B $5 m$
We know that,
Volume of room
$= l e n g t h \times b r e a d t h \times h e i g h t$
Area of the floor
$= l e n g t h \times b r e a d t h$

Given that,
Volume of the room
$= 660 m^{3}$
Area of the floor
$= 132 m^{2}$

Now,
Volume of room
= Area of floor $\times$ Height of the room
[From above data]
$\Rightarrow 660 = 132 \times h$
$\Rightarrow 5 m = h$

Hence, the height of the room is $5 m$ .
