The observer in the figure is positioned so that the far edge of the bottom of the empty glass (not to scale) is just visible. When the glass is filled to the top with water, the center of the bottom of the glass is just visible to the observer. Find the height, H, of the glass, given that its width is W= 6.6cm .(Figure 1)Express your answer using two significant figures.
