If each student needs 1.6 m of floor area inside a classroom of 12.5 m * 64 m * 5 m, then no. of students it can accommodate is 500 and each student would get 8 m³ of air.

Step-by-step explanation:

Length of the classroom, l = 12.5 m

Breadth of the classroom, b = 64 m

Height of the classroom, h = 5 m

Step 1:

Area of the floor of the classroom = l * b = 12.5 * 64 = 800 m²

Floor Area required by each student is given = 1.6 m²

Therefore,

No. of students the classroom can accommodate = \frac{800}{1.6} = 500

Step 2:

Now we know that,  

[The volume of the classroom] = [Volume of Air occupied by the classroom ]

⇒ l*b*h = Volume of Air occupied by the classroom

⇒ 12.5 * 64 * 5 = Volume of Air occupied by the classroom

⇒ 12.5 * 64 * 5 = Volume of Air occupied by the classroom

Volume of Air occupied by the classroom = 4000 m³

Therefore,

The cubic metres of air each student would get,

= [Volume of Air occupied by the classroom] / [No. of students the classroom can accommodate]

= [4000] / [500]

= 8 m³

Answer:

No. os students = 50

Volume = 8 m³

Step-by-step explanation:

  • Number of Students = Area of Floor ÷ Area occupied by each student

= (12.5×6.4)m²÷1.6m²

= 50 Students

  • Volume of Air for each Student = Volume of Room ÷ No. of Students

=(12.5×6.4×5)÷50

=8m³
