Question

The dimensions of a room are $3m\times 4m\times 10m$. It has $5$ men, then the amount of air for each man available is:

• A. $48m^3$
• B. $36m^3$
• C. $24m^3$
• D. $120m^3$

Answer 1

The correct option is C $24m^3$

Length of the room$=3m$

Breadth of the room$=4m$

Height of the room$=10m$

$\therefore$Volume of the room$=$Quantity of air present in the room

$=(3\times 4\times 10)m^3$

$=120m^3$

Total number of people in room$=5$

$\therefore$ Air of each person$=\frac{120}{5}=24m^3$
