You would put the item on a triple beam Balance or any other type of scale
Use a digital mass scale or a triple-beam-balance scale to find the mass of a regular solid.
A balance or scale is typically used to find the mass of a solid. The solid is placed on the balance, and its mass is measured in units such as grams or kilograms.
mass/volume
mass/volume=density
i dont know u answer it
You need to know the mass of the solid.
You measure its mass and volume and then density = mass/volume.
find the weight and devide it by constant "g=9.81".
mass over volume
To find the center of mass of a solid hemisphere, you can divide it into elementary components, such as disks or cylindrical shells, and integrate their individual masses over the hemisphere's volume. By dividing the mass-weighted points by the total mass, you can determine the coordinates of the center of mass in three dimensions.
To find the density of a solid heavier than water, you need to measure its mass using a scale and then measure its volume using displacement method or geometric calculation. Finally, divide the mass by the volume to calculate the density of the solid.
If this rectangular solid is actually in your possession, then you would measure it and calculate the volume, after which you can derive the density by dividing the mass by the volume. If it is not in your possession, then you are clearly being asked to call upon your psychic powers to solve this problem.
