一个几何体的表面展开图如图所示，则这个几何体是____ 

①皮肤②胃黏膜③神经细胞④蚯蚓⑤细胞内蛋白质等化合物⑥病毒⑦同一片草地上的所有山羊⑧一池塘中的所有鱼类⑨一片森林⑩一池塘中的所有生物

观察下列等式 $\frac{1}{1\times 2}$ =1﹣ $\frac{1}{2}$ ， $\frac{1}{2\times 3}$ = $\frac{1}{2}$ ﹣ $\frac{1}{3}$ ， $\frac{1}{3\times 4}$ = $\frac{1}{3}$ ﹣ $\frac{1}{4}$ ，将以上三个等式两边分别相加得： $\frac{1}{1\times 2}$ + $\frac{1}{2\times 3}$ + $\frac{1}{3\times 4}$ =1﹣ $\frac{1}{2}$ + $\frac{1}{2}$ ﹣ $\frac{1}{3}$ + $\frac{1}{3}$ ﹣ $\frac{1}{4}$ =1﹣ $\frac{1}{4}$ = $\frac{3}{4}$ ．
