Layout
The best layout our engine found puts 28 with the 760 mm side along the length and 3 turned with the 1140 mm side along the length. That covers 94.9% of the floor.
The same 31 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 31 for the CP5, so the CP5 pallets cover 26.9 m² against 24.0 m² for EPAL 1.
The door opening is 2,340 mm wide, so the CP5, carried narrow side first, clears it by 1,580 mm.

Height and weight
Empty CP5 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 496 across the 31 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 CP5.
If all 31 clearance positions are filled in one layer, the guideline payload allows on average 859 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.
