We divide the overburden thickness by ore thickness to get the stripping ratio For example if we have an overburden thickness of 80m and ore thickness of 50 m , then the stripping ratio will be: 80/50= 1.6
30-50 km.
the yield strength of Q345B is 345MPa for thicknesses <= 16 mm. 325MPa for 16 mm < thickness <= 35 mm. 295MPa for 35 mm < thickness <= 50 mm. 275MPa for 50 mm < thickness <= 100 mm.
All U.S. bills are approximately 0.11 mm thick. I.e. a stack of 9 of them is about 1 mm high. In inches, a single bill is about 0.0043 inches thick. A standard bundle of 50 bills ($50 to $5000) is about 5.5. mm high (0.215 in at 233 to the inch).

Between 50 and 100 km
Actually Grant is on a $50 bill,
Yes. It does have a thickness, even though that is very small.
U.S. Grant appears on the $50 bill.
Yes a 50 dollar bill is red
