The half-life of carbon-14 is 5370 years. The carbon-14 levels in a fossil indicate that 6 half-lives have passed. How old is the fossil?

If the half-life of carbon-14 is 5,370 years and 6 half-lives have passed, you can calculate the age of the fossil by multiplying the half-life by the number of half-lives: 5,370 years × 6 = 32,220 years. Therefore, the fossil is approximately 32,220 years old.
