A room 6m by 4.5 m contains 108m3 of air. Find the height of the room.

Answer»

Answer:

Given :

Length of ROOM = 6m.

Breadth of room = 4.5 m

Solution :

Let the height of the room be H m.

Volume of AIR = 108 m³

⇒ lbh = 108

⇒ 6 × 4.5 × h = 108

⇒ 27 h = 108

⇒ h = \FRAC{108}{27}

⇒ h = 4 m.

∴ height of the room = 4 m.
