3.ThelengthofacoldO TS OFDE Square metre.storage is double its breadth. Its height is 3m. thearea of its four walls(216 m3)(including doors) is 108m2. Find its volume1 4

Answer»

let the breadth of the storage be b metrestherefore the length of the storage l=2b metresheight 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 =1082(2b+b)3=1082 x 3b x 3=10818b=108b=6m

now l=2b=2x6=12ml=12m

now volume of the storage is l x b x h= 12m x 6m x 3m= 216m^3
