If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days
I think i know this one. it's 3,281.
-1? I'm guessing the least
There will be 6 / 1/3 = 6 x 3 = 18, so 18 sections will be created from the 6 meter board
