Layout
The best layout our engine found puts 18 turned with the 1300 mm side along the length. That covers 91.0% of the floor.
The same 18 pallets still fit after leaving 100 mm of length and 50 mm of width free for handling, so this layout has room to spare.
Floor and door
The 40 ft dry container has 28.3 m² of floor (305 sq ft) inside. In the same box an EPAL 1 takes 25 positions against 18 for the CP4, so the CP4 pallets cover 25.7 m² against 24.0 m² for EPAL 1.
The door opening is 2,340 mm wide, so the CP4, carried narrow side first, clears it by 1,240 mm.

Height and weight
Empty CP4 pallets are 138 mm high. The lower of the inside height (2,383 mm) and the door height (2,280 mm) is 2,280 mm, so 16 fit in one stack and 288 across the 18 clearance positions, weighing about not published, which is over the 26,650 kg guideline payload.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,140 mm tall, which leaves 1,002 mm for goods on each CP4.
If all 18 clearance positions are filled in one layer, the guideline payload allows on average 1,480 kg of goods per pallet.

How this is computed
The engine tries every split of the deck into rows of pallets placed one way and rows placed the other way, along the length and across the width, and keeps the arrangement with the most pallets. It does not overhang, mix in other pallet sizes or allow for bulging goods. The methodology page explains each step, and the load planner runs the same code on your own dimensions.
