Question

Find the volume of Air in a room measuring 4cm by 5m which is 3m high

Answer 1

Hi there !!

We are given the

length of the room as 4 cm = 0.04 m ,
Breadth of the room as 5 m and height as 3 m

So , its clear that the shape of the room is cuboid. SO , here we are asked to find the volume of air in the room.

So ,
To find the volume of air trapped , we just have to find the volume of the cuboidal room.

Volume of a cuboid = lbh

= 0.04 × 5 × 3

= 0.6 cm³


So ,
Volume of air trapped in the room is 0.6 cm³

Answer 2

Given,

Length = 4 cm

= 0.04 m

Breadth = 5 m

Height = 3 m

Volume of cuboidal room = l * b * h

= 0.04 * 5 * 3

= 0.6 m³

So, volume of air in the room = 0.6 m³ Ans.
