Question

The length of a cold storage is double its breadth. Its height is 3m. The area of its four walls is 108m^.find its volume.

Answer 1

Given that height = 3m.

Given that length is double its breadth i.e if the breadth is x and length will be 2x.

Given that Area = 108m.

                 2(l + b) * h = 108

                 2(2x + x)  * 3= 108

                  6x * 3 = 108

                     18x = 108

                        x = 6.

If breadth = 6 then the length will be 2 * 6 = 12.

Volume = l * b * h

              = 12  * 6 * 3

             = 216 m^3.


Hope this helps!

Answer 2

Answer:

b=x

l=2x

h=3

108=2(l+b)

108=2(2x+x)3

54=3x×3

54=9x

54/9=6x

x=breath=6

2x=length=2×6=12

volume=l×b×h

=12×6×3

=216 cm^2
