What's the size of the protons? You can look up the diameter and the area of a sphere (if you assume they are spheres) is (4/3)*pi*4^3. Do you want the Hg in cubic inches or cubic centimeters. If cc, then
8.5 in x (2.54 cm/in) = ? cm
Area of Hg is pi*r^2
thickness is 0.25 in and that is
0.25 in x (2.54 cm/in) = ?
8.5 in x (2.54 cm/in) = ? cm
Area of Hg is pi*r^2

0.25 in x (2.54 cm/in) = ?
