Not sure where to start

Question

I’m trying to figure out how many grams of silver it would take to make a solid 8mm bead. I Found a calculator online that Said (d, ∅ 1 mm)= .0055g x 8= .044g per every 8mm beads. It comes out to being only 2.596g for the amount of beads needed. This doesn’t seem correct to me. Am I missing something ?

Answer 1

Erm, when you increase the dimension of a 3 dimensional object by n, you increase the volume by n^3 -- assuming I'm reading this right, an 8mm solid bead has `8^3 = 512` as much gold as a 1mm bead. You could also just calculate the volume, find the density of gold, and look up current prices (of course, melting and reshaping the gold would cost something too)
