What arguments are there for human history before civilization occurred

Well civilization started in the Neolithic age. (the new age). Civilization didn't really grow well in the Paleolithic. (the old age)

Some people argue about how the first humans, austrosapiens (I think that's how its spelled), migrated. There is physical proof that the first humans migrated from Africa but everyone argues about how they migrated. Were the world continents together? Or did they find some other way?

Most people don't believe that the continents were together at one time.

24.

A cube has 6 faces. One face = 9 cm^2

9 x 6 = 54 cm^2

25. Calculate the area of each side then add them all together.

26. Multiply the length by the width by the height.

27. Surface are is squared, so you need to square the scale factor.

Volume is cubed, so you need to cube the scale factor.

28. As the number of sides increase the surface area and volume would increase.

29. The relationship between the two is the value of PI.

If you know the diameter, you multiply that by PI for the circumference.

If you know the circumference divide that by PI to get the diameter.

30.  This is the same question as 26 above.
