We have a large very thin sheet of rice paper which pile at the rate of 1 thousand sheets to the inch.
Supposing we tear the paper in half an put the two pieces together on top of each other and we tear them in half and put the 4 pieces together in a pile and then we tear them again in half and put the eight pieces in a pile and we continue like this upto 50 times, can u tell how high the final stack of paper would be?

After 50 times the number of papers will be 2^50=1125899906842624

for 1000 pages it is 1 inch then for 1125899906842624 pages it is 1125899906842.624 Inches

1/1000*2^50=5.02inches(approx)

(50*log(2))/3*log(10)=>(50*0.3010)/(3*1)

=>(15.05)/3 =>5.016 inches

total number of papers 1st cut 2, 2nd = 4, 3rd = 8, 4th = 16, 50th = 2 ^ 50

Thick ness of sheets all togather = (2 ^ 50)/1000

let x = (2 ^ 50)/1000

Log x = log {(2^50)/1000) = Log 2^50 - Log 1000 = 50Log 2 - 3 =

= 50 x 0.3010 - 3
log x = 15.0515-3 = 12.05144
x = Anti log of 12.05144
= 1125899907000

as the papers are stacked one above the other even after cutting.u'll ultimately u'll get one stack having 2^49 papers (=1->2->4->......50times is 2^49)so height is 2^49/1000 inches =5.6295*10^11inches
