Question

the breadth of a hall is twice its height and half its length find its dimensions if the volume of the hall is 1000 M

Answer 1

let height be 'x'
then breadth is 2x
length is 4x
given volume is 1000M
volume of rectangle is l×b×h
l×b×h=1000
x×2x×4x=1000
8x^3=1000
(2x)^3= 10^3
2x = 10
x =5
hence ,
height=x= 5
breadth=2x=10
length=4x= 20
