Atoms are the tiny, complex building blocks of all matter. In a
chemistry or physics class you might be asked to calculate the volume of
an atom. This calculation is often done as a preparatory step in a more
complex calculation to determine the volume of the atom's nucleus.
Although the study of atoms can be difficult, the calculation of an
atom's volume is not.
The atom is simply explained to be in the shape of cube.
"A unit cell" simply means that the atom has several cells but each one of them is 1.9 to the power of negative 22 cm cubed.
To calculate the volume, which is cubed shape, find the dimensions by using the provided volume cm3.
Calculate the cubic radius of an atom by multiplying the atomic radius
by itself three times. For example, if the atomic radius is 5, you would
multiply 5 by itself three times, which equals a cubic radius of 125.
Hope that helps

First you have to realize that cell and the atom are both spheres, and that the cell is at the center of the atom.
The formula to calculate the volume of a sphere is:
