let
height if room be x cm
so breadth of room= 2x cm
ATQ
breadth is half of length
so length of room =4x cm
now
volume=512cm^3
so x*2x*4x = 512
8x^3 =512
x^3 = 64
so x = 4 CM = height
2x = 8 CM = breadth
4x = 16cm = length

let x be the breadth of the room
so the height is 2x
and length is x/2
volume of the room =512m^3
=l×b×h
=x × x/2 × 2x=512
x^3=512
x=cube root of 512
so x is 8
so length is 4
breadth is 8
height is 16
so the height is 2x
and length is x/2
volume of the room =512m^3
=l×b×h
=x × x/2 × 2x=512
x^3=512
x=cube root of 512
so x is 8
so length is 4
breadth is 8
height is 16
