Layout
The best layout our engine found puts all 20 in a square grid. That covers 98.4% of the floor.
Leaving 100 mm of length and 50 mm of width free for handling costs 10 positions: the clearance layout puts all 10 in a square grid.
Floor and door
The 40 ft high cube reefer container has 26.4 m² of floor (284 sq ft) inside. In the same box an EPAL 1 takes 23 positions against 20 for the CP3, so the CP3 pallets cover 26.0 m² against 22.1 m² for EPAL 1.
The door opening is 2,290 mm wide, so the CP3, carried narrow side first, clears it by 1,150 mm.

Height and weight
Empty CP3 pallets are 138 mm high. The lower of the inside height (2,537 mm) and the door height (2,502 mm) is 2,502 mm, so 18 fit in one stack and 180 across the 10 clearance positions, weighing about not published, which is over the 30,560 kg guideline payload.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,251 mm tall, which leaves 1,113 mm for goods on each CP3.
If all 10 clearance positions are filled in one layer, the guideline payload allows on average 3,056 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.
