Thx for the points
Dimensional Analysis is the way you want to go

State the vertex and axis of symmetry of the graph of y=ax^2+c
General form of quadratic equation is 
There is no bx in our given equation, so we put 0x
Given equation can be written as 
a=a , b=0
Now we use formula to find vertex


Now we plug in 0 for 'a' and find out y

So our vertex is (0,c)
The axis of symmetry at x coordinate of vertex
So x=0 is our axis of symmetry
8 x 2 1/4 = 18
the stack is 18 in. thick.
Hope this helps!!
