Question

The length,breadth and height of a classroom are in the ratio 3:2:1 .A student requires 3600 cm^2 of floor area to sit .If maximum of 150 students can sit in classroom,find dimensions of classroom.

Answer 1

let the length = 3x
breadth = 2x
height = x

Area require to sit = 3600

150 students require = 3600 × 150

L × B = 540000

3x × 2x = 540000


$6x {}^{2} = 540000$

$x {}^{2} = 540000 \div 6 = 90000$


$x = \sqrt{90000} = 300$

Length = 3x = 3×300 = 900cm

Breadth = 2x = 2×300 = 600cm

Height = x = 300cm



Thanks

Answer 2

Answer:

60,40

I have done both the steps bcz in my book the height is given 8 cm in place of 9cm so if I put this my answer is coming 53.33 & if the height is given 6 cm in place of 9 cm then the answer will come 40 cubes....
