Imagine that each layer of this step pyramid is made from identical,cube-shaped blocks of stone.The bottom layer has seven rows of stones with seven stones in each row.The next laer has five rows of stones with five stones in each row.The third layer has three rows of stones with three stones in each row.And the top layer is a single stone.
1)Some of the stones are completely hidden in this arrangement,so they are not exposed to rain,wind,and the other elements.
a.How many stones are exposed?
b.How can you explain your rsult without counting the stones layer by layer?
2)Each stone is shaped like a cube,so each has six faces,although not all the faces of each stone are exposed.If there were a big rainstorm and all the exposed faces got wet,how many stones would have one wet face?Two wet faces?Tree wet faces?Four wet faces?Five wet faces?Six wet faces?
3)Now imagine alarger versionof this structure,in which the bottom layer has 25 rows of stones with 25 stones in each row.The next layer,centered on the first,has 23 rows of stones with 23 stones in each row.The next layer has 21 rows of stones with 21 stones in each row,and so on.
a.How manylayersdoes this structure have?
b.How many exposed stones does this structure have?
c.How many stones in this structure have one exposed face?Two exposed faces?Three exposed faces?Four exposed faces?Five exposed faces?Six exposed faces?
4)How can you generalize your results from Questions 1 through 求翻译啊

这是个益智题么?大意是

1. 假设有一个用完全相同的正方体石块堆砌而成的阶梯金字塔.最底层的石块按7x7（共49个）排列,上面一层是5x5,然后在再上面一层是3x3,然后顶上只有一个石块.
这样一来,有的石块完全被包裹,风吹不着雨淋不着,倍儿安全.
a.露出来的石块有几个?
b.要知道这个答案,有没有除了一层层数以外的办法?（我估计是有个公式可以推导）
2. 石块有6个面,不是每个面都会露出来.如果这个金字塔被雨淋了,会淋湿几个面?
3. 如果这个金字塔再大点,底层是按25x25铺设,上层是23x23,然后是21x21,以此类推.
a.这个金字塔有几层?
b.有几块石块是露在外面的?
c.露一面的石块有几个?两面的有几个?三、四、五、六面的有几个?
从1到3,你总结出规律了吗?

打字很费劲的,满意的话别忘了给分哦亲~~
