The "atomic packing fraction" is the fraction of a crystal's volume occupied by atoms, assuming that the atoms are solid spheres which touch each other, For fee. crystals it in 0.74, whilst for b.c.c. crystals it is 0.68. A cubic ingot of low-carbon steel with an f.c.c. crystal structure is cooled from 1000"C to just ABOVE 912"C, at which temperature it retains an for structure and has dimensions of exactly imx 1m x 1m. It is then cooled to just below 912"C and its crystal structure transforms to b.c.c. The Ingot expands as it changes crystal structure, What are the ingot's cube edge dimensions after transformation (ignoring the slight thermal contraction due to the small change in temperature]?
