Question

The length of a cold storage is double its breadth. Height is 3m the area of its four walls including doors is 108m2 find its volume

Answer 1

 The area of the wals=LSA of the given storage

now let the breadth be x

so length =2x

height=3m

so the LSA of the storage srea = 2 h(l+b)

108m=2 X 3(2x + x)

108/6=3x

=18/3=x=6

Length=12

so the the volume wil be

=12 X 6 X 3

=216m sq

Hope it helps...
