All measurements are in centimeters, so we don't have to worry about units.

Volume of each rod:

%28pi%29%28r%5E2%29%28h%29 = %283.14%29%284%5E2%29%2820%29

Perform that calculation; then divide 28134.4 by the result to find the number of rods.

(The given numbers are good; the result you will get if you do the calculations correctly is a whole number.)
