Puzzle 433

Assuming that there are nearly 7,000,000,000 (7 billion) people on Earth, estimate the size of number you'd get if you multiplied together the number of fingers on everyone's hands.

For this calculation, it might be easier to count a thumb as a finger.

How many zeroes would this number have? How many beaches of sand would this be?

How far into the galaxy could we reach if your answer was converted to miles?

How many zebras would you need to have this many hairs?

During the recent BrainBashers cipher convention, a binary code contest took place.

The contest consisted of a binary code transmission where the spaces between the letters were missing and there was no punctuation.

Each letter of the alphabet was translated into its binary equivalent based on its position in the alphabet.

a=1         b=10        c=11        d=100
e=101       f=110       g=111       h=1000
i=1001      j=1010      k=1011      l=1100
m=1101      n=1110      o=1111      p=10000
q=10001     r=10010     s=10011     t=10100
u=10101     v=10110     w=10111     x=11000
y=11001     z=11010
