1.	A classroom is 10m long, 6.4m wide and 5m high. If each student be given 1.6m2 of the floor area, how many students can be accommodated in the room? How many cubic metres of air would each student get?
Answer» The dimensions of classroom are Length = 10m Breadth = 6.4m Height = 5m It is given that the floor area for each student = 1.6m² So the number of students = area of room/floor area for each student By substituting the values Number of students = (10 × 6.4)/1.6 So we get Number of students = 40 So the air required by each student = Volume of room/ number of students We know that Volume of room = l × b × h By substituting the values Volume of room = 10 × 6.4 × 5 = 320 m³ So we get Air required by each student = 320/40 = 8m³ Therefore, the number of students that can be accommodated in the room is 40 and the air required by each student is 8m³.

Answer»

The dimensions of classroom are

Length = 10m

Breadth = 6.4m

Height = 5m

It is given that the floor area for each student = 1.6m²

So the number of students = area of room/floor area for each student

By substituting the values

Number of students = (10 × 6.4)/1.6

So we get

Number of students = 40

So the air required by each student = Volume of room/ number of students

We know that Volume of room = l × b × h

By substituting the values

Volume of room = 10 × 6.4 × 5 = 320 m³

So we get

Air required by each student = 320/40 = 8m³

Therefore, the number of students that can be accommodated in the room is 40 and the air required by each student is 8m³.
