Solution

Let h = the height of all the boards = ?
Let x = the number of boards =9
Let t = the thickness of each board = 3*2/3 cm = 0.78 inches
We know that the number of boards * the thickness of each board = the total height.
So we can express this in an equation as follows:
 
x * t = h
 
We know t and x, so enter them in:
9*0.78= 7.02 inch
height = 7.02 inch
height =17.83 cm
