m³ of air. The side of the cube is

Answer 1

Answer :-

• The side of the room is 6m.

Step-by-step explanation :

To Find :-

• The side of cube

Solution :-

Given that,

• Number of persons can stay in a room which is cubical in shape = 8 persons
• Each person requires = 27m³ of air

Hence, 8 persons requires

=> ( 8 × 27 )m³

=> 216m³

Now, We can find out the side of cubical room by applying the formula of " Volume of cube " As we know that,

Volume of cube = a³ cubic units,

Where,

• a = side of cube

=> a³ = Volume

=> a³ = 216

=> a³ = 6 × 6 × 6

=> a = 6

Hence,

• The side of the room is 6m.
