I suggest that a candlepin bowling ball cannot have a volume of 48 inches cubed since that is huge. 48 inches cubed = 48"*48"*48" = (48*2.54cm)*(48*2.54cm)*(48*2.54cm) >120*120*120cm3 = 1 728 000 cm3 which is more than 300 times larger than the 5274 cm cubed ball.

1 cm cubed = 1 cm X 1 cm X 1 cm 1 cm = .01 m, so 1 cm cubed = .01 m X .01 m X .01 m Therefore, 1 cm cubed = .000001 m cubed, and 243 cm cubed = 243 X .000001 = .000243 m cubed. In summary, multiply cm cubed by .000001 to get m cubed.

Because centimeters cubed is a unit of volume, not weight. The two might take up the same amount of space, but iron is much more dense and as such weighs more.

The density must be 22.5 GRAMS per cm cubed, not 22.5 cm cubed. Then, Density = Mass/Volume implies Mass = Density*Volume = 22.5 * 5.42 = 121.95 grams.

cm measures length and cm cubed measures volume so you wouldn't convert one to the other. If you had a box you could measure the height, width and depth in cms and multiply all 3 to get the volume in cm cubed.
