Scale - 1 cm : 6 ft
1/6 = x/30
(1/6 is the scale factor, 30 is the real life measurement, and x is the height of the shrine on paper).
Cross multiply as you normally would with a proportion.
6x = 30
Divide both sides by 6 to get "x" alone.
x = 5
I'm not sure about what you mean when you refer to the "equation editor", but the final answer would be 5 cm. Hope this helps!
