The ten million yuan if according to all are 100 yuan of large banknotes, then according to the length of a one hundred yuan banknote is 155 millimeters, the width of 77 millimeters, the thickness of about 0.1 millimeters, the weight of 1.15 grams or so (the new and the old coins do not differ much). So a 10,000 dollar bill is probably around 1 centimeter thick. And 10 million yuan would make a pile of a large chunk of cash with a length of 77.5 centimeters, a width of 77 centimeters, and a height of about 20 centimeters. Based on this calculation, 10 million RMB is roughly 150 kilograms (that's 0.15 tons). Ninety million yuan is 0.15*9=1.35t.
