How to calculate the angle of six copper weight
The cross-sectional area multiplied by the length of the hexagonal bar multiplied by the proportion of the proportion of units, pay attention to
Six angle bar length is l, hexagonal section length was a, the density of copper is xIs the quality of m= (3 V 3) /2a - L
balanceChasing the answerThe first thing I think about it is how you divide it into six triangles
According to the physics book, you should throw it into the water, measure the volume of the overflow water, and then count the density
