Instrument tray: Can a 400×200 tray hold 400 shielded cables of 1×3×1.5 dimensions? What is the maximum number that can be placed there?

1X3X1.5: Roughly, it can be considered as one large circle (the insulating layer) containing 3 smaller circles of the same diameter (the wires). Thus, 1.5 mm is the radius of the large circle. Using the formula for the area of a circle, we get 3.14X0.0015X0.0015X400 (the total area covered by the 400 wires). The area of a rectangle is 0.4X0.2. Compare the two values – no need for me to explain further, right?
