3. Sample Calculations: (cylinder only)
I. Average Diameter:
D aveg = (D1+D2+D3+D4)/4
D aveg = (12.735mm+12.74mm+12.72mm+12.73mm)/4
D aveg = 50.925mm/4
D aveg = 12.73125 mm
II. Corrected Average Diamter:
CAD = D aveg – Zero reading
CAD = 12.73125mm – (+0.01mm)
CAD = 12.72125 mm
CAD = 1.272125 cm
III. Volume of the cylinder
V = π * (Daveg)2* haveg/4
V = π * (1.272125 cm)2*(5.00)/4
V = 6.355057155 cm3
IV. Density
ρ = mass/volume
ρ = 56.6 grams/6.355057155 cm3
ρ = 8.906292835 grams/cm3

5. Percent Error:
a) Cylinder
% error = |T – E| *100% / T
%error = |8.93 grams/cm3 – 8.91 grams/cm3|*100% / 8.93 grams/cm3
%error = 0.2%
6. Percent Difference: (Block)
%diff. = |Exp1 – Exp2| * 100 % / ((Exp1+Exp2)/2)
%diff. = |0.73 gm/cm3 – 0.71 gm/cm3 | * 100% /((0.73 gm/cm3 + 0.71 gm/cm3)/2)
%diff. = 3. %
