Question

DJ Vani's CD cabinet is four-and-a-half times as long as it is wide, which is a third of its height.
If its volume is 864,000 cc, what is the width of the CD cabinet?

Answer 1

40 cm

Width- x
Height- 3x
Lenght- 4.5x
Volume- 864000 cc
Volume = W*H*L=13.5*x^3=864000 cc => x=40 cm
Width - 40 cm
