Question

The length, width and height of a hall are in the ratio 8:6:3.If the volume is 18000cu.m , find the height of the hall.

Answer 1

Answer:

Let ratio of length breadth and height be 8x:6x:3x

Then

volume= lbh

18000=8X × 6X × 3X

18000=48X² × 3X

18000=144X³

18000/144= X³

125=x³

x³=125

X=³√125

X= 5

Height= 3x

= 3×5

=15
