文 [1]与文 [2 ]分别给出了已知四面体六条棱的长求四面体体积的两个计算公式 ,读后获益匪浅 ,只是觉得其形式不易记忆 ,文 [2 ]的公式虽然较文 [1]的简单 ,由于其几何特征不明显也觉得难以记住 .本文推出一个新的六棱求积公式与读者共享 ,并给出已知六棱长求四面体对棱距离的 In [1] and [2], two formulas for calculating the tetrahedral volume of a known tetrahedron with six edges were given respectively. After reading, they benefited a lot, but they found that their forms are not easy to remember. [2] Although the formula is simpler than that in [1], it is difficult to remember because of its inconspicuous geometric features. This paper presents a new hexagonal quadrature formula to share with readers, and gives the known hexagonal long tetrahedron to the distance of the edge. of
