cubic light year
An interesting but peculiar question to say the least...
The way to proceed is to find out how many tablespoons are in a cubic meter
(a volume whose size we know):
1 tablespoon = 1.479 x 10-5
Next, how many cubic meters are in a cubic light-year? We can find that by cubing the number of meters in a light-year
1 light-year = 9.461 x 1015
1 cubic light-year = 8.467 x 1047
Finally, divide out the m3
to get the number of tablespoons in a cubic light-year:
8.467 x 1047
/ 1.479 x 10-5
= 5.725 x 1052
That's alot of tablespoons. If we assume that each tablespoon was a spoon 6" long, then that many tablespoons placed end to end would stretch across the entire visable universe more than a trillion times for each dollar in Bill Gate's net worth. It's a very difficult number to comprehend.
