1. Find volume of spheres = 4/3pr3 and multiply by 4 since there are 4 spheres.
2. Find volume of units cell = l 3 = (2Ö2r)3.
3. Find volume of empty space = vol unit cell minus volume of spheres.
4. Divide volume empty space by volume of unit cell.
It works out to 25.952

How do you calculate 145.75 plus 2.3x10-1 in scientific notation and significant figures?
145.75+2.3*10^-1 145.75+0.23 145.98 As 2.3*10^-1 has two significant figures, our answer must have two significant figures 145.98 150 As the 5.98 rounds up to the nearest significant figure 1.5*10^2
What is the greatest number that rounds to 700?
That depends on how many significant figures you are talking about.If three significant figures then 700 is the largest that rounds to 700.If four significant figures are to be rounded to three significant figures then 700.4If five significant figures are to be rounded to three significant figures then 700.49If six significant figures are to be rounded to three significant figures then 700.499etc.
