Question

c) The area of a room 21sq m, if the height 5m, find the volume of
air in the room​

Answer 1

Answer:

3

The answer is 10500dm

Step-by-step explanation:

2

The area of the floor (A)=21m

Height of the room (h)=5m

We have to find the volume of the air in the room

So, capacity of the room to contain air,

V=A×h

=21×5

2

=105 m

3

=105×(10dm)

[ 1m=10dm ]

3

=105×1000dm

3

=10500dm

3

Volume of the air contained in the room is 10500 dm

${ \pink{ \underbrace{ \red{ \boxed{ \mathcal{ \fcolorbox{pink}{orange}{ \red{ANSWER}}}}}}}}$

The area of the floor (A)=15m

2

Height of the room (h)=4m

We have to find the volume of the air in the room

So, capacity of the room to contain air,

V=A×h

=15×4

=60m

3

=60×(10dm)

3

[ 1m=10dm ]

=60×1000dm

3

=60,000dm

3

Volume of the air contained in the room is 60,000dm
