已知直四棱柱的底面是边长为a的正方形,高为h,体积为V,表面积等于S(1)当a=2,h=3时,分别求V和S (2)当V=12,S=32时,求2/a+1/h的值我理解力不好.
已知直四棱柱的底面是边长为a的正方形高为h体积为v表面积等于s当v=12,是=32时求2/a+1/h的值
已知直四棱柱的底面是边长为a的正方形,高为h,体积为V,表面积等于S.(1)当a=2,h=3时,已知直四棱柱的底面是边长为a的正方形,高为h,体积为V,表面积等于S.(1)当a=2,h=3时,分别求V和S.(2)当V=12,
设a.b是正整数,且a-b.3b.a+b(a>2b)构成一直角三角形边长,则这个三角形的任一边的长不可能是( )A12 B 13 C 14 D15
如果把直角三角形的三边都减少相同的长度,仍能构成三角形,则这个新的三角形的形状是 A锐角三角形 B直角三角形 C钝角三角形 D由减少的长度决定
以2a.2b.2c的长为边的三条线段能组成直角三角形吗?,为什么?
