How are volume units related to length?
Here's all you need to know to convert between volumes (i.e. m^3 to cm^3). Volume is distance x distance x distance. Any formula you think about. Cube=L^3 or LxWxH, sphere is 4/3 pi x r^3 (r is distance), cylinder = pi x r^2 x L (r x 2 and L). Why is this? because volume extends to the 3rd dimension. What used confuse me was when my maths teacher said that there were 1,000,000 cm^3 in a metre cubed. I knew that...

I can’t add one of them positive, one...
