I think you mean the cd = .27
Therefore, your cda would be the cd X (frontal area in ft^2). An estimate of your frontal area is the height X width X 0.8.
Height in feet: 59.3"/12 = 4.94'
Width in feet: 70.3"/12 = 5.86'
Frontal Area: 4.94' X 5.86' = 28.94 ft^2 X 0.8 = 23.15 ft^2
cdA = 0.27 X 23.15 ft^2 =
6.25 ft^2
