WebOkay well to start off let's guesstimate the average diameter of a grain of sand to be about half a millimeter (5E-4 meter). I am going to assume that a grain of sand is in the shape of a sphere so we'd use the formula: V=(4/3)πr 3 to find the volume of 1 grain of sand. If we use 2.5xE-4 meter for "r" we get roughly 6.545E-11 cubic meter as the volume for 1 …
