Well, sweetheart, that's actually something you should ask your parents or an adult you trust about, but I will tell you some facts about that and leave the rest for your parents to tell you. One reason why it might be so small is because you aren't fully grown yet and you might need to go through a growth spourt (Or "puburty" as most people call it) before it gets any bigger. And plus, sometimes it's just small and it remains small. But that's not even half the facts, if you want to know more, go ask your parents sweetheart.
It will grow just as the rest of your body will grow.

Which is it, inches or centimeters? If you describe a length as 8 in cm, I don't know what you mean. In any event, 8 cm would be much more normal than 8 in, which would be unusually long. But in either case, I wouldn't worry about it.
That depends on what the '8' are. 8 feet. . . . . 243.8 cm (rounded) 8 inches. . . . . 20.32 cm (rounded) 8 miles . . . 1,287,475 cm (rounded) 8 millimeters . . . . . 0.8 cm (rounded) 8 smoots . . . . . . 170.2 cm (rounded) 8 furlongs. . . 160,934 cm (rounded) 8 meters. . . . . . . 800 cm (rounded)
8+10+8+10= 36 cm
two feet
8 cm / 2 m = 8 cm / 200 cm = 8/200 and you can simplify that fraction if you wish.
8 cm
If one edge is 8 cm, then all edges would be the same. Therefore: the volume is 8 × 8 × 8 = 512 cubic centimetres.
