Question

A classroom is 5m long , 2.5m broad and 3.6 m high. If each students is given 0.5m² of the floor area, then how many cubic meters or air would each students get?

Answer 1

Answer:

first find its volume

then divide by student area

Answer 2

Each student will get 1.8 cubic m

Step-by-step explanation:

Length of Classroom = 5 m

Breadth of classroom = 2.5 m

Height of classroom = 3.6 m

Area of floor =$Length \times Breadth = 5 \times 2.5 = 12.5 m^2$

Area occupied by 1 student = 0.5 sq.m.

No. of students = $\frac{\text{Total area of floor}}{\text{Area occupied by 1 student}} = \frac{12.5}{0.5}=25$

Volume of Classroom = $Length \times Breadth \times Height = 5 \times 2.5 \times 3.6 = 45 m^3$

So, Volume of air = 45 cubic m

Each student will get air = $\frac{45}{25}=1.8m^3$

Hence Each student will get 1.8 cubic m
