Take width x Height of the plenum, Calculate Equivalent Diameter, Then for the specified air flow rate, Find the Static loss factor( feet / 100 feet of WC). then Calculate Friction Head ie,
((Feet/100 ft of WC x Length of the plenum)/100)

You cannot "calculate" the front of a box. You can calculate its dmensions, or its area but calculating it does not make sense. As for calculating its size or area, the answer will depend on what information you have and what you require.
two times the length of the box plus height
how to calculate carton price
you do length times width

Please give the exact method of sizing a plenum box
The Trox plenum box radial air discharge ensure a high degree of comfort.
The exact method of sizing a plenum box is putting the numbers in their tens.
If limiting friction is the same as static friction, then I have an answer, because static friction means that the objects in contact do not move. For example, if you place a box on the table, it does not move, as there is static friction between the box and the table.
The large plastic box on top with the air filter in it could be called a plenum.The large plastic box on top with the air filter in it could be called a plenum.
Heater plenum is the same as the heater box and it spans the width of the passenger side dash behind the glove box. Check heatertreater.net for pictures.
It is mounted on the Plenum.
Here in Louisville, KY General purpose runs for about 75$ a box and Plenum is $250.
The BDA is mounted to the top of the plenum between the plenum and the duct work just behind the glove box
Static friction
If it is a tuned port injected motor, it is under the plenum. The plenum is the big grey aluminum box with 8 funny looking pipes, called runners, connected to it.
