木材材积表高3.5米中间直径0.33米有多少方木头
长3.5米；因为是日志参数，所以计算体积时作为计算中心直径依据的小直径可以用百度日志计算。快速体积计算器。
木材材积表:木材长3.5米大头直径0.47米小头直径0.4米请帮忙算一下是多少立方？
你可以计算两个圆锥体的面积，然后将它们相减。较大圆锥体的面积为(0.235*0.235*3.14/3-0.2*0.2*3.14/3)*3.5你！
小径3.5米4---16公分材积各是多少？
本标准适用于计算所有树种的木材蓄积量。1、直径4~12cm的小圆木体积按公式V=0.7854L{D+0.45L+0.2}^2->100002确定。
直径大于14cm的木材体积由公式确定V=0.7854L{D+0.5L+0.005L^2+0.000125L·(14-L)^2·(D-10)}^210000式中：V----体积，m3；L——标距，m；D——表径，cm.3。
测量值在“记录测试尺寸和测量值”中指定。
4.直径为4~6cm的原木的体积数据必须保留至小数点后四位。
直径为8厘米或以上的原木的体积数据必须保留至小数点后三位。
