A classroom is 5 m long 2.5 m broad and 3.6 m high. if each student is given o.5 m × m of the floor area , then how many cubic meters of air would each student get?
Answers
Answer:
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^2Length×Breadth=5×2.5=12.5m
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
Area occupied by 1 student
Total area of floor
=
0.5
12.5
=25
Volume of Classroom = Length \times Breadth \times Height = 5 \times 2.5 \times 3.6 = 45 m^3Length×Breadth×Height=5×2.5×3.6=45m
3
So, Volume of air = 45 cubic m
Each student will get air = \frac{45}{25}=1.8m^3
25
45
=1.8m
3
Hence Each student will get 1.8 cubic m
