At the beginning, and a centimeter apart each, is my guess.

Also to point out about the last brain teaser, I would have said compressed gasses (as it seems recent planetary science has led to the idea that outter planets would not have enough rocky material that far out to form large rocky cores. Mainly from evidence from exosolar systems, but ultimately I suppose it is the accepted answer).

Then at 9

At 4.5

Divide that space in 3 so you have 1.5 and 3.0

And divide the 3.0 marking into 3 as well.

all full centimeter values from 1 to 36 cm directly from the ruler. how do you find 5cm?Originally posted by cytokinesis

Nah, thats cheating, you must be able to read all full centimeter values from 1 to 36 cm directly from the ruler. no copying or using the ruler twice.after you have the first centimetre then you can copy the 1 cm length over the ruler to measure everything

1, 3, 6, 13, 20, 27, 31, and 35 centimeters on my ruler.
