Solution
The area of the floor(A) = 15 m2
Height of the room (h) = 4 m
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
=60 m3
= 60 × (10 cm)3 {Since , i m = 10 cm }
= 60 × 1000 cm3
= 60,000 cm3
Volume of the air contained in the room is 60,000 cm3.
