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.
If two perfect spheres of different sizes have the same mass, then the larger ball has a lower density and the smaller ball has a higher density. This is because density is the amount of mass in a given volume, and density is obviously higher if there is a smaller volume for a given amount of mass.
Sizes or amounts of matter in objects can be compared by measuring their mass, volume, or density. Mass is the amount of matter in an object, volume is the space that the object occupies, and density is the mass per unit volume. By measuring these properties, you can compare the sizes or amounts of matter in different objects.
No, a copper penny and a large copper bell cannot have the same density because their sizes and shapes are different. Density is defined as mass divided by volume, so even though they are made of the same material (copper), the penny and the bell have different masses and volumes, resulting in different densities.
A machine with two circular devices of different sizes could be a gear system, where gears of varying diameters are used to transfer rotational motion or change the speed and torque of a mechanical system.
Sauce pans come in a range of measures.
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.
Iron can come in pieces of different sizes.
Kleenex comes in boxes of different sizes.
For the creativity of the person building, mostly to let the builder use different sizes of pieces in their creations. It also is used in sets if it is needed.
no, what determines whether they will float or not is their density

Yes there are different sizes of trash receptacles. You could observe the different sizes of trash receptacles on amazon.com. They offer cheap prices and durable products.
There is no answer to that. An e-mail can be different sizes, so it could be many small messages or a smaller amount of large messages, but typically a mix of all different sizes.There is no answer to that.

You can separate them by their colors, copper having a pinkish tint and aluminum a gray tint. You could use your fingers or a pair of forceps to pick the pieces apart. If they are of different sizes, you could use a screened sieve to sort them.

This means that the different proportions are not the same. You could have different sizes or have the shapes change unproportionally.
