Given:
Length of classroom(l)= 10 m
Width of classroom (b) = 6.4 m
Height of classroom (h) = 5 m
Floor area given to each student = 1.6 m²
Let the total number of students be x.
Area of floor of a classroom = Total number of students × floor area occupied by each student
l × b = x × 1.6
10 × 6.4 = x × 1.6
x= (10 ×6.4 )/1.6
x= 10 × 4 = 40
Total number of students accommodated in the room is 40
Volume of air in the classroom = Volume of classroom =l × b × h
= 10 × 6.4 ×5= 320 m³
40 students got 320 m³ of air
1 student would get air = 320/40= 8m³
Hence, Total number of students accommodated in the room is 40 & each student will get 8 m³ of air.
