1 cu cm = 0.001 l = 1/1000 l = 1 ml
9=l in a gb
A = w*l so 184 = w*23 or w = 184/23 = 8 cm

1000 cu cm = 1 l → 1500 cc = 1500 ÷ 1000 l = 1.5 l
L = 9 w = 9

1000 mL = 1 L so 9000 mL = 9 L. Simple enough for you, I hope!
It is impossible to say. Let L be ANY number such that 4.5 ≤ L < 9 cm and let B = (9 - L) cm. Then for every one of the infinite number of values of L, there will be a different rectangle whose perimeter will be 18 cm.
You would use square cm. 1m = 100cm A= 100 cm * 34 cm = 3400 cm2
