Parallel placement: three boxes are placed in parallel on the first floor, which can save space, but attention should be paid to whether the length and width of the boxes are suitable for the size of the container and whether there is enough space between the boxes to prevent squeezing or sliding.
Vertical placement: three boxes are placed vertically on the first floor, which can increase stability, but attention should be paid to whether the height of the boxes is suitable for the height of the container and whether the weight of the boxes is evenly distributed to prevent tilting or collapse.
Staggered placement: Staggered placement of three boxes on the first floor can improve the utilization rate, but attention should be paid to whether the shape of the boxes is suitable for staggered placement and whether the angle of the boxes is suitable to prevent the gap from being too large or too small.
