Correct Answer - Option 1 : 15 m

Given:

Volume of room = 1680 m^{3}

Area of floor = 112 m^{2}

Formula used:

The volume of Cuboid = l × b × h

Area of floor = l × b

where,

l = length, b = breadth, h = height

Calculations:

Volume of room = 1680 m3

⇒ l × b × h = 1680

⇒ (112) × h = 1680

⇒ h = 1680/112

⇒ h = 15 m

∴ The height of the room is 15 m.
