Question

The length of a cold storage hole is 15 meter and breath is 2.5 times of it's height. If the area of it's four walls is 275 m^2. 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!
