WebThe Sahara Desert. Let’s assume that all the grains of sand are spherical and of equal size. If so, they will ‘pack together’ with maximal compaction, such that the spheres themselves fill 68% of the total volume. If the diameter of the grains is on average 1 mm, this would give 1.30 × 10 9 (1,300 million) grains in one cubic metre of sand. WebCounting the grains of sand on a beach or extrapolating the number of grains of sand on the planet is based on too many assumptions.
