Total volume of air = length * breadth * height = 15*12*7.5 = 1350 cubic metre
Number of children = Total volume of air / Volume of air required for 1 child
= 1350 / 3.6 = 375
Number of children are 375

Answer:
375 children can be accommodated in this class room
Step-by-step explanation:
total volume of room
= length * breadth * height
= 15 * 12 * 7.5
= 1350 m^3
air needed by 1 student = 3.6m^3
number of students = 1350/3.6
= 375
375 children can be accommodated in this class room
