A standard pallet is 1.2M x 1.2M. Boxes look as if they divide equally through the centre of the pallet, meaning the boxes are 600mm long. It is reasonable to say that the pallet would be loaded equally with box shape only. To utilise maximum space, it is likely the boxes are stacked in layers of 2 X 4 600x300x~200mm boxes. There look to be 6 layers of boxes, so (2X4) X 6 = 48 boxes per pallet. Unsure of possible third pallet in background behind the two clearly depicted pallets.
Yes they are both a circle shape, GREAT DIGGING ANON!
Yeah nice.
