Wow. I've lived with metric for most of my life, but I've never heard of some of these.
21) k stands for kilo, and means 1000. 150 kL = 150,000 L
22) This threw me ! d stands for 1/10, but it's (almost) NEVER used. There are 10 decimetres in a metre, but that's about it.
So 38 dkm = 1/10 of 38 km = 1/10 of 38,000 m = 3,800 m
23) Well ! We're talking grams and decigrams, but hg ? That's a new one for me...
24) 1cm cubed (or 1 c.c. on a syringe) = 1 mL
25) m stands for milli and means 1/1000. 0.036s = 36ms
26) c stands for centi, means 1/100. Combine that with milli, and you find 10 mm = 1cm. So 0.67cm = 6.7mm
---- Edit ----
Oh! The second link is a help. dg is a decigram, or 1/10 of a gram. hg is hectogram, or 100 grams.
So 5.4hg = 540g = 5,400dg.
In real life, you'd call it 0.54kg, or about a pound on the old scale.

Hon, first off, do your own homework if you intend to learn anything at all and second 21=1.5L. It is just simple math. So go do it!

.15L
3.8m
.0054dg or 5.4 x 10 to the power of -3
1mL
.000036 or 3.6 x 10 to the power of -5
.067mm
good luck
