Answer 2

Step-by-step explanation:

Let the height of the hall be

′

h

′

m.

Area of floor =l×b=20×16=320m

2

Area of root =l×b=20×16=320m

2

Sum of areas of four walls =2(l+b)h=2(20+16)h=72h m

2

Now, 72h=(320+320)=640

h=

72

640

=

9

80

m

Volume of hall =l×b×h=20×16×

9

80

=

9

25600

m

3

Ratio of height to volume =

25600/9

800/9

=

25600

80

=

320
