Answer:
Volume of face centered cubic cell=
Explanation:
Consider the face centered cubic cell:
1 atom at each corner of cube.
1 atom at center of each face.
Consider the one face (ABCD) as shown in attachment for calculation:
Length of the all sides of face centered cubic cell is L.
Volume of face centered cubic cell= L^3
Now Consider the figure shown in attachment:
According to Pythagoras theorem on ΔADC.
(a is the atomic radius)
(Put in the formula of Volume)
Volume of face centered cubic cell= L^3
Volume of face centered cubic cell= 
Volume of face centered cubic cell= 
Volume of face centered cubic cell=
