Question

The area of four walls of the room is 51 cm^2. If the room is 5 m long and 3.5m wide find the height of the room

Answer 1

Solutions :-

Given :
The area of four walls of the room is 51 cm².
And the room is 5 m long and 3.5m wide.

Find the height of the room :-

We know that,
Curved surface area of cuboid = 2h (l + b)
=> 51 = 2h (5 + 3.5)
=> 51 = 2h × 8.5
=> 51 = 17h
=> 51/17 = h = 3


Hence,
The height of the Room = 3 m
