You can put this solution on YOUR website!
m/r = (1 inch * (1/12) ft/inch ) / (5.4 ft)
m/r = (1/12 ft) / (5.4 ft)
---
m/r = (1/12 ft) / (5.4 ft)
m/13.5 = (1/12 ft) / (5.4 ft)
m = (13.5 ft)(1/12 ft) / (5.4 ft)
m = (13.5)(1/12)/(5.4)
m = 0.2083333 ft
m = (0.2083333 ft)*(12 inch/ft)
m = 2.5 in
---
the model is 2.5 inches high
