Example:
   All sides/edges of a cube are equal in measure.
   Side = 4 units
   Volume = (4)³
   Volume = 64 units³

Increase the side by 1% or 0.01
   Side = 4 (1.01) units
   Side =  4.04 units
    
   Volume = (4.04)³
   Volume = 65.94 units³

Rate of increase in volume, when a side in increased by 1%:

   =  65.94 units³ - 64 units³
     ----------------------------------  x 100
                   64 units³
  
   = 1.94 units³
    -----------------  x  100
        64 units³

=   3.03%  or  3%
