Question

the length of a cold storage is doubled its breadth. its height is 3 metres. the area of its four walls is 180 m sq. find its volume​

Answer 1

Answer:

give the height -3m

given the length is double its breadth i.e if the breadth is a x and length and length will be 2x

given the area -108m

2(1+b)*h-108 m

2(2×+x)*3=108m

6×*3=108

18× =108

x=6

if breadth is =6 then the length will be 2*6=12

volume =1* b* h*

=12* 6* 3*

x=6

Explanation:

if breadth is 6 length 2*6=12

volume =I* b* h* v

12* 6* 3*

216m^3

hope it is a helpful

Answer 2

${ \huge{ \underline{ \underline{ \sf{ \green{GivEn : }}}}}}$

• The length of a cold storage is doubled its breadth.

• Height = 3m

• Area of four walls = 108 m²

${ \huge{ \underline{ \underline{ \sf{ \green{To \: find :}}}}}}$

• What's the volume of cuboid?

Formula to be used :-

• Area of four walls = 2 ( l + b ) × h

• Volume of cuboid = l × b × h

Where,

l = Length

b = Breadth

h = Height

Let the breadth be y.

Given that,

The length of a cold storage is doubled its breadth.

Therefore,

Length = 2y

According to the question :-

⟶ Area of four walls = 108 m²

⟶ 2 ( 2y + y) × 3 = 108

⟶ 6 × 3y = 108

⟶ 18y = 108

⟶ y = 6 m

Hence,

Length = 2y = 12 m

Breadth = 6 m

Now, find the volume of cold store

Volume of the cold storage = l × b × h

= 12 × 6 × 3

= 216 m³

Verification :-

⟶ Area of four walls = 108 m²

⟶ 2 ( l + b ) × h = 108

⟶ 2 ( 12 + 6) × 3 =108

⟶ 108 = 108
