The length of a cold storage is double its breadth. Its height is 3 metres. The area of its four walls(including doors) is 108 m2. Find its volume.

• let the breadth of the storage be b metres
  therefore the length of the storage l=2b metres
  height of the storage =3 metres
  
  now the area of the four wall = 2(l+b)h
  
  we already know that area= 108 m2 (given)
  => 2(l+b)h =108
  => 2(2b+b)3=108
  => 2 x 3b x 3=108
  => 18b=108
  => b=6m
  
  now l=2b
  =2x6
  =12m
  =>l=12m
  
  now volume of the storage is l x b x h= 12m x 6m x 3m
  = 216m^3

• answer 216m³
  
  let xbe breadth ,then 2x is the length
  
  then 2x*3*2+x*3*2=108
  
  12x+6x=108
  
  x=108/18=6
  
  length 12,breadth 6 ,height 3
  
  volume=12*6*3=216

• => 2(l+b)h =108
  => 2(2b+b)3=108
  => 2 x 3b x 3=108
  => 18b=108
  => b=6m
  
  now l=2b
  =2x6
  =12m
  =>l=12m
  
  now volume of the storage is l x b x h= 12m x 6m x 3m
  = 216m^3

• Area of four walls =2(l+b)h =108
  l=2b(given), h=3 then
  2(3b)*3=108 i.e 18b=108 then b=6, l=12 ,h=3 volume=6*12*3=216

• let b be breadth of cold storage.
  then length is equal to 2b.
  area = l*b
  area = 2b*b=108
  b=10.38
  length=20.76
  volume=10.38*20.76*3=62.20

• area of 4-walls is 108 m^2. let breadth is of x mtrs, so length is 2x metrs. now, 3x+3x+6x+6x=108. so, x=6. length is 12. volume=12*6*3=216 m^3
