将数字排列成三维数组的最快方法是什么？

import math

def arrange_numbers(numbers):
    # 计算三维数组的维度
    size = int(math.ceil(len(numbers) ** (1/3)))
    
    # 创建三维数组
    cube = [[[0 for _ in range(size)] for _ in range(size)] for _ in range(size)]
    
    # 填充三维数组
    for i, num in enumerate(numbers):
        x = i % size
        y = (i // size) % size
        z = i // (size * size)
        cube[x][y][z] = num
    
    return cube

# 示例输入
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

# 调用函数进行排列
result = arrange_numbers(numbers)

# 打印结果
for z in range(len(result)):
    for y in range(len(result[z])):
        for x in range(len(result[z][y])):
            print(result[x][y][z], end=' ')
        print()
    print()
