## To obtain the density of an object, you would need to know its mass and volume. The formula for density is given as D = M / V, where D represents density, M represents mass, and V represents volume.

To determine the mass of an object, you would need to weigh it using a scale or balance. Place the object on the scale and measure the weight in kilograms or grams. This measurement will provide you with the mass value for the object.

Finding the volume of an object can depend on its shape. For regular shapes like cubes, spheres, or cylinders, you can use specific formulas to calculate their volume. For example, the volume of a cube is found by multiplying the length, width, and height of the cube. In the case of irregular objects, you can measure the volume by submerging them in a graduated cylinder filled with water.

To measure the volume using a graduated cylinder, follow these steps:

1. Fill a graduated cylinder with a known volume of water.

2. Measure and record the initial water level (before adding the object).

3. Gently place the object into the graduated cylinder, ensuring it is fully submerged in the water.

4. Measure and record the final water level.

5. Calculate the volume by subtracting the initial water level from the final water level. This difference represents the volume of the object.

Once you have obtained both the mass and volume of an object, you can then use the formula D = M / V to calculate its density.
