								## Description
							 |

| 
								 | 
							
								<section id="description">覆盖尺寸为3 x 2 x 1的长方体上每个可见面的最小立方体数量为22。 <p>如果我们在这个固体上添加第二层,则需要四十六个立方体来覆盖每个可见面,第三层需要七十八个立方体,第四层需要一百一十八个立方体来覆盖每个可见面。然而,尺寸为5 x 1 x 1的长方体上的第一层也需要22个立方体;类似地,尺寸为5 x 3 x 1,7 x 2 x 1和11 x 1 x 1的长方体上的第一层都包含四十六个立方体。我们将定义C(n)来表示在其一个层中包含n个立方体的长方体的数量。因此,C(22)= 2,C(46)= 4,C(78)= 5,并且C(118)= 8.结果,154是n的最小值,其中C(n)= 10。找到n的最小值,其中C(n)= 1000。 </p></section>
