Answer:
1.5 billion years = 3.33 meters
From the end 2.22\times 10^{-5} meters is the distance of written history.
Step-by-step explanation:
Age of earth is 4.5 billion years and we have to represent the history of earth (from birth to present ) with a 10 meter long timeline.
So on the scale every meter will represent 4.5/10 = 0.45 billion years.
∵ 0.45 billion years represent the distance = 1 meter on scale.
∴ 1 billion years will be represented by =
∴ For 1.5 billion years distance will be =
Now we have to measure the length of written history from the end of the timeline.
Since written human history extends about 10000 yrs back means distance on timeline = = from the end.
To find volume you use the formula length×width×height. a cube has all same measurements. So 3×3×3 is 27. the volume is 27 inches cubed
