Question

50 students sit in a classroom.Each student requires 9 m2 on the floor and 108 m3 in space. If the length of the room is 25 m, find the breadth and height of the classroom.

Answer 1

Hi friend✋✋✋✋
---------------
Your answer
-------------------

Number of students that can sit in a classroom = 50 students

Floor area required by each student = 9 m²

Length of the room = 25 m

Area of the room = (50 × 9) m² = 450 m²
So,
------

Area = length × breadth

=> 450 = 25 × breadth

=> Breadth = 450/25

=> Breadth = 18 m

Again,
-----------

volume of space required by each student = 108 m³


Volume of the classroom = ( 108 × 50) m³ = 5400 m³

Then,
-----------

Volume = Length × Breadth × Height

=> 5400 = 25 × 18 × height

=> Height = 5400/(25 × 18)

=> Height = 3888 m
