Question

how many c.c. is in cubic inches

Answer 1

In 1 cubic inch there are 16.387 cubic centimetres.

We know that 2.54 cm is equivalent to 1 inch
2.54 cm   =    1 inch
    
   to get to cubic inch you cube the inches thus essentially                      
   ( 1 inch  x  1inch  x  1 inch ) 
 
  to get to the cubic centimetre you would do the same 
     ( 2.54 cm  x  2.54 cm  x  2.54 cm)  =  16.387
