Calculate the density of a metal object that has a dull surface and an irregular shape. It has a mass of 321 grams and a volume of 45.2 cm 3.

mass = volume x density

4512

7.10 g/cm cubed

To calculate the density of an object, we use the equation:

Density = Mass / Volume

In this case, the mass of the metal object is given as 321 grams, and the volume is given as 45.2 cm^3.

To calculate the density, divide the mass by the volume:

Density = 321 grams / 45.2 cm^3

Now, we need to make sure that the units of mass and volume are compatible. Grams and cubic centimeters (cm^3) are compatible units, so we can proceed with the calculation.

Density = 7.11 grams/cm^3

Therefore, the density of the metal object is 7.11 grams/cm^3.
