Question

15. A classroom is 10 m long, 6.4 m wide and 5 m high. If each student
be given 1.6 m² of the floor area, how many students can be
accommodated in the room? How many cubic metres of air would each
student get?​

Answer 1

total total area will be 10 metre into 6.4 metre into 5 metre so the total area will be 320 m and now the area accommodated bye one student is 1.6 m so total number of student the room will accommodate will be 320 divided / by 1.6 w which will give answer 200 so the room will accommodate 200 students hope it's help you please mark me brainliest

Answer 2

Solution :-

l = Length

b = Breadth

h = Height

a = Area

Let the number of students be 'x'

Area of floor total number of students × Area occupied by each student

Substituting them,

$\sf \dfrac{10 \times 6}{1.5} =x$

$\sf x=40x=40$

Volume of classroom = Area occupied in class room

By the formula,

$\underline{\boxed{\sf Volume \ of \ cuboid=Length \times Breadth \times Height}}$

Substituting their values,

Volume of classroom = 10 × 6 × 4

Volume = 240 m³

240 m³ = Air occupied by the classroom

Now,

Each will get = Volume of the classroom / Number of students

Substituting their values,

Each will get =$\frac {240}{40} = 6 m^3$
