D=6cm, h=6cm, and the volume of a zongzi V= 1/3sh (one third of the bottom area times the height) =1/3 * 2π r * h =1/3 * 2π * 6/2 * 6 =/kloc-.

Weight per cubic meter 1.8 kg, so a zongzi weighs 0.03768 * 1.8 = 0.06782 kg. ..

Then 600 pieces weigh 0.06782*600=40.69kg, less than 45kg.

So enough!

Very detailed, no, please keep asking questions!
