Question

The area of the floor of a room is 15 m². If its height is 4 m, then the volume of the air contained in the room is

Options

•  60 dm³

•  600 dm³

•  6000 dm³

• 60000 dm³

Answer 1

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.
