Mass and total volume
To determine the density of a metal, you need to know its mass (in grams) and its volume (in cubic centimeters). Density is calculated by dividing the mass of the metal by its volume.
Two common pieces of equipment used to find density are a balance and a graduated cylinder. The balance is used to measure the mass of the object, while the graduated cylinder is used to measure the volume of the object. By dividing the mass by the volume, you can determine the density of the object.
Cutting a piece of glass into four smaller pieces would not change the density of the glass. Density is a property of the material itself and remains constant regardless of its shape or size.
You are confusing density with weight. Two pieces of wood of the same density but different sizes have different weights. Density, you could say, is like hardness. If you take a 6 foot piece of wood, and cut 2 feet from it, the two pieces of wood are definitely different weights but the same hardness. Since they came from the same original piece of wood, they almost have to be the same density. There are some types of wood that have such high density that they will not float on water.
You still need to divide mass by volume. The problem here is finding the volume. In some cases you can submerge the object in a liquid, and see how much liquid it displaces. You can also calculate its volume mathematically, using integration. This basically means dividing it into small pieces (not the real object, only in the calculations), for example shapes that approximate rectangular blocks, calculate the volume of each piece, and add everything up.

No, cutting a candy bar in half will not change its density. Density is a constant property of a substance, and cutting it into smaller pieces does not alter its mass or volume, which are the factors that determine density.
It means: * Calculate the density of an object * Calculate the density of its pieces * Compare

To determine the number of 1x4 lumber pieces needed for your project, calculate the total length required and divide by the length of each piece.
The chemical formula of the compound (e.g., H2O for water) and the molar masses of the elements present in the compound are needed to determine the ratio of elements. The molar masses are required to calculate the molar ratios of the elements in the compound.
If a cube of jello is cut into two pieces the density of the pieces do not change.
Yes, a crayon has greater density than pieces of crayon, assuming the pieces are not heated and mashed together. That's because the crayon has density X and air has a lower density Y. Some combination of X and Y will always be less than X.
To demonstrate that two pieces of wood of different sizes have the same density, you can calculate the density of each piece using the formula density = mass/volume. First, weigh each piece to obtain their masses. Then, measure their dimensions to determine their volumes, often by using geometric formulas or water displacement. If both calculations yield the same density value for each piece, it confirms that they have the same density despite differing sizes.
To calculate population density, two pieces of information are needed: the total population of a specific area and the land area of that same area. By dividing the population by the land area, population density can be determined, usually expressed as the number of individuals per square unit (e.g., individuals per square mile or individuals per square kilometer).
You do not need fancy lab equipment.Basically you need to determine two pieces of information1) The mass of the "irregular" shape (use a scale)2) The volume of the shape (use water displacement in a bucket/tub to find volume)Take the mass / volume and you have density.
