my math is really bad, but i'd guess it'd be 4cm coz 2 of the sides would be the same length, since the top and the bottom are likely to be longer than the side lengths that connect them, i'd guess that it's for. ROFL sozz, im not too good with using formulas :S
1.8=9/5
0.03=3/100
so it'd be 9/5 *divided by* 3/100
and so u flip the second equation over and times across
so you'd get 9/5 * 100/3
