Question

A classroom is $10m$ long $6.4m$ broad and$5m$ high. If each student be given $1.6m^2$ of the floor area, find the amount of air each student will get ?

Answer 1

Step 1: Find the number of student

Length of classroom $=10m$

Breadth of classroom $=6.4m$

Height of classroom $=5m$

$\text{Area of classroom = length × breadth}$

$=10\times 6.4=64m^2$

Each student is given$1.6m^2$ of the floor area.

Total number of students $=\frac{64}{1.6}=40$

Step 2: Find the amount of air each student will get

$\text{Volume of classroom = length × breadth × height}$

$=10\times 6.4\times 5=320m^3$

Air occupied by class$=320m^3$

Amount of air each student will get $=\frac{Volumeofclassroom}{no.ofstudents}=\frac{320}{40}=8m^3$.

Hence, the amount of air each student will get is $8m^3$.
