when 1.783 is rounded to the nearest whole number,the result is how much great than when 1.783 is rounded to the nearest tenth?
还有一个金字塔的高度问题:
说金字塔底面是正方形,四个三角形都是等边三角形而且跟正方形相等,记做M.若高是H,求问用M表示H.
OG第三版401页19题

嗯,第一题问1.783约到个位和约到十分位,差多少.约到个位是2,约到十分位是1.8,差便为0.2,如果楼主不会做这种题的话,我看还不要勉强了 -.-
第二题给出正金字塔,底正方形边长为m,金字塔高为h,4个等边三角形的腰各位e,且e=m,问用m表h
想象立体单面三角形,定点为V,变h和e,这个直角三角形的底是底正方形斜边的一半,及0.5√(2m^2) = 0.5m√(2),以勾股定理得出.已知e=m,且带h变的直角三角形又有底边0.5m√(2),再用勾股,得出 h = m/√(2)
楼主好运吧
