一、测量固体密度的方法1.用刻度尺、天平测形状规则的固体物质的密度.只要这种固体物质的形状是规则的:长方体、正方体、圆柱体、圆锥体、圆台体、球体,都可以用刻度尺测量它的几何尺寸,然后根据体积公式计算出它的体积V,并用天平称出它的质量m, A method of measuring the density of the solid 1. With a scale, the density of the regular determination of the shape of solid matter, as long as the shape of the solid material is regular: cuboids, cubes, cylinders, cones, cones, spheres, all You can use a ruler to measure its geometry, and then calculate its volume V according to the volumetric formula, and use the balance to weigh its mass, m,
