Question

24. The length, breadth and height of a room are 5 m, 4.5 m and 3 m respectively. Find
the volume of the air it contains.
[Hint: Volume of the air in the room = Volume of the room.]
95 A water tank is 3 m long 9 m broad and 1 m deen Harman 1​

Answer 1

Answer:

Explanation:

volume of air it contains = volume of cuboid.

volume of cuboid= l*b*h

 here, l = 5m

          b= 4.5 m

          h = 3m

∴volume of air = 5 * 4.5*3

                        = 67.5 m³

Answer 2

Answer:

Volume of the air = 67.5 m^3

Explanation:

Given,

Lenght of room = 5 m

Breadth of room = 4.5 m

Height of room = 3 m

Volume of air = Lenght x Breath x Height

                      = 5*4.5*3

                      = 67.5 m^3

       

* the volume of air is 67.5 m ^3
