The scale factor is 1 : 64 , not 1 : 64 inches,
ratios don't have units
It means that 1 inch in the model is 64 inches in reality
1 foot in the model is 64 feet in reality
1 metre in the mode is 64 metres in reality
etc
x feet in the mode is 20 feet in reality
x/1 = 20/64
x = 5/16 feet or .3125 feet or 3 3/4 inches
